I’m new here. First post so forgive me if it’s in the wrong thread. I’ve got a 2019 Silverado 2500 W/T which is basically my daily driver, and the first HD truck I’ve owned. The recommended tire pressure is an insane 60psi front, and 80psi in the back (80 being the max for the tire). I understand the need for this when towing/hauling, but with the HD suspension on top of that, it makes for a pretty rough ride. My question is how much can I soften up the tires when driving with no load, without causing any handling problems, or any other potential unknown issues from lowering the tire pressure? Any help appreciated. Thanks

Who has replaced their factory rear driveshaft: Why? What brand or what type of custom build? Type of mods to driveshaft? Steel vs. Aluminum heavier/thicker walled/stronger Length added to accommodate lift kit? Heavier U Joints? Two piece? Cost? Results? Additional Advice or comments? Feel free to add in any field I neglected to mention. *I searched, but did not find a dedicated replacement driveshaft thread.

Performance Parts for 3.0L Duramax (LM2)
btj_z71 posted a topic in 2019-2023 Silverado & Sierra Mods
Has anyone used this PSI Power Tuner or found where others have used this? I found the product on two different sites; the 2nd URL has better details on the product. I'm skeptical on this product, being that no other tuners have released products for the 3.0L Duramax (LM2). PSI Power 2020 3.0L Duramax Performance Module (Truck Edition) | Thoroughbred Diesel Agricultural Diesel PSI Power Module 2020 3.0L GM Duramax (parleysdieselperformance.com) Also, what about these two products? https://afepower.com/afe-power-50-70064t-momentum-hd-cold-air-intake-system-w-pro-10r-filter#overview https://afepower.com/afe-power-77-44014-scorcher-hd-module#overview And this? https://www.sbfilters.com/cold-air-intakes/silverado-sierra-1500-duramax-3-0-intake-75-5137?variant_id=712 -
I am looking for advice on the best short tube headers and CAT back exhaust system that will bolt on. I am not looking for annoyingly loud, but something that will help pull my boat down the road, while still maintaining the luxury feel of the Denali. I do plan to do a tune once the upgrades are done. I have the K&N CAI for her already, but I am have seen so many options, I'm just looking for someone who had a similar engine and if they like the mods and would spend the money again! Thanks for your help!!! -
I just rolled over 30k miles on my cc4wd, '16 with the 5.3, and 8 speed. I have read more than a handful of people recommending getting a tune (usually when the warranty runs out)...so this is my first post about that...before I really start my research, I wanted to get some real life experiences and expectations... I get that i can make my truck run like a banshee...but I don't need a hot rod...I just want to get optimal power and optimal MPG under normal driving...I rarely tow anything...and I drive pretty conservatively... in my scenario...would you still recommend a tune? what can I expect to get out of one? is there any that are the best value, what about getting a tune off the shelf verses going to a shop and getting it done? if I lose any mpg's it probably wouldnt be worth it...so I need to at least stay the same or improve...so keep that in mind... any insight and opinions would be appreciated!

Looking for a new exhaust for my 6.2 AT4. Leaning toward the Borla Atak system. Appears to deliver some sound and performance gains. Talked with Borla Engineers and they say absolutely NO drone on the Atak system ay any RPM and no problem with cylinder deactivation. I just don't want it to be too loud at cruising speed but have not heard of any complaints. Ready to pull the trigger on this but looking for any first hand experience with the Atak system. Thanks

Part # from GM site 84520923. Could not find answers to the questions about this Performance part from GM. So I am paying back to this forum with an unboxing of the filter to answer some of the questions. Is it a disposable filter? How often do you change it? Do you need to tune the truck to take advantage of this filter? Still to be answered in use: Are there any improvement (subjectively by feel and by mileage)? Will it improve anything including idle smoothness? Slightest change to the sound of the intake? 10X more expensive than stock filter is being put to test. I get that nobody in the right frame of mind would spend 10x on the drop-in filter but I did use my GM points. Let's see... Paper manual that came with GM Performance Air Filter- 14 replies

I recently acquired a 1951 Chevrolet 6100 missing its engine and would like to refurbish it. However, Instead of putting in the original engine (Chevrolet 235) I am looking for an engine that came out in the next 10-15 years to put in my truck that will out put 200+ horsepower without being out of touch with the truck. Any advice would be greatly appreciated.

Hi All, Im new here and was hoping to get some advice on doing some performance upgrades on my 2012 GMC Sierra 1500. 5.3 liters. Just to share some trials I have experienced with this truck. A couple of months past the 5 year warranty #7 cyl lifter collapsed! What a terrible design! GMC didn’t do anything to compensate me for the problem that I’ve come to learn is a frequent one. I replaced the lifter. Now I want to delete the Active fuel management (AFM). I was thinking of using this programmer.(DiabloSport 8245 inTune i3 Platinum Performance Programmer 3rd Generation inTune inTune i3 Platinum Performance Programmer. Any feedback on this would be awesome. Also the shifting on the transmission is very rough.(it drops down a gear and would like to throw me and my passages through the windshield!) I would also like to put a cold air induction headers and new exhaust. If any of you have tips On the brand would be appreciated. And do you think I should put a performance chip in also? Any Advice would be greatly appreciated. Thanks Ken. Also I would like to note that my truck only has 50,000 miles on it. I still can’t believe GMC would’nt of helped me out somewhat.

Hey guys and gals I was hoping y’all could answer a question of mine. I currently own a 2019 Silverado trail boss with the 5.3 and 6 speed transmission. A mechanic told me the transmission is a ticking time bomb if I do any performance mods. Such as a cam swap and tune. So I explained my plan for the future. Cold air intake, flow master exhaust, headers, tune and cam swap. He said if I do any of the big changes to the engine the tranny may go out. The reason why is because the stock transmission was only made to handle the stock HP and TQ. Have any of y’all had an issue like this after some big performance mods? -
Attached is a link to a kit I'm intrigued by because it does a few things I'm quite interested in... Namely: - Appears to be more geared towards improving the handling rather than just dropping the ride height. - IS NOT a gonzo drop... I'm really only wanting to do a 2/4 at the most. This is a 2/3 if one uses the entire kit. Belltech's site doesn't say much about it. Belltech has been in the game for a good long while, so I have to assume that they know what they are doing. Belltech is also in bed with KW Automotive... That should also speak to the legitness of Belltech in the here and now. Anywho... here it is: https://www.belltech.com/products/belltech/lowering/complete-lowering-kits/performance-handling-kits/belltech-performance-handling-kit-07-18-1-2-ton-silverado-sierra-all-cabs-short-bed-985hk.html Practical knowledge and insights regarding the kit would be awesome. Thoughts from the collective braintrust are also welcome. Thanks y'all!

Hello there ladies and gentlemen! I come to you guys again for help finding something... A good tuner chip/monitor. Here's the catch: I want a tuner that has a monitor so I can see how my trucks doing while I’m driving. I’ve heard that the DiabloSport intune i3 is a good tuner for our trucks, but I don’t see any mounting options... Unless I buy a phone mount for my windshield? Really not looking into blackbear at the moment, even though I’ve heard so many good things about it. I'd like to keep my price at below 400. I am very interested in the intune i3, but can I mount it with a windshield mount for a phone or is there an actual mount sold separately for it? Can I even use it as a monitor as well? What programmer/monitor do you guys recommend for my price range? -
Ok so I've installed the Airaid MIT, AEM dry high flow filter, and Borla muffler. Now I need a tune to bring all this together. I'd love to pay a custom shop to do this professionally, but unfortunately I can't find one near me, which is weird because I live in the freakin racing capitol of the world. I'm looking for a very basic tune. My primary concerns are MPG's, turn off V4, and account for the 33" tires I put on. If I can gain a bit of performance from this tune, awesome, but that is not my primary concern. Anyhow, I've seen a ton of tuners out there from the cheap "plug in and leave" type, to the full blown $500 tuners. So what is everyone's opinion on getting a tune? Is it really all the hype others make it out to be, is it worth it, and is it really necessary with the mods I've done? Will the cheap "plug in and leave" type suffice, or are they junk? Are the $500 tuners worth it, and if so, are they easy enough from a beginner to use (I'm a beginner but I'm also very tech savy)....OR, should I just keep looking for a pro shop to do it for me? Thanks fellas!

Alright, so I've literally spent probably 8 hours or so researching on this forum about exhaust and intake upgrades. (I have a '17 Sierra 5.3) Obviously the CAI horse has been beaten to death on pretty much every forum immaginable. I'm a Mechanical Engineer by trade so data goes a long way with me. From what I've seen, on this new Ecotec engine, you don't really gain a whole lot with a CIA, many have just resorted to the Airaid MIT, but even that only see's minimal improvements and only around 5,500 rpm. So I just opted to go with the AEM dry filter for a bit more flow, and call it a day. I've even thought about doing the airbox mod, but when I got everything apart, the cross sectional area of the square hole in the airbox looks to be about the same as the cross sectional area of the intake tube diameter...So whats the point? (unless I'm missing something). So I just left it at the new AEM filter and called it a day. I have the level and 33's on this truck, so I'm not looking to drag race it. Just get it to breath as well as possible. Any input or opinions on this setup would be appreciated. Now on to the exhaust. I plan to just do a muffler swap, so I bought a new Borla Pro XS. I've seen a TON of debate on "leave the resonator, remove the resonator, leave the flapper, remove the flapper". I dont want this thing to be loud. I just want it to sound good and "natural". So as I said, I just opted to leave everything stock and replace the muffler. HOWEVER, I scooted under the truck this morning just to take a look, and now I'm completely baffled (pun intended). It looks to me like the resonator on this truck is AFTER the muffler!?!? You have the giant oil barrel shaped muffler with the flapper just in front of it, then downstream you have a (roughly) 8" diameter round barrel which I can only assume is the resonator? So my question is, is that correct, or am I missing something? ...maybe I have it backwards? Also, is leaving the flapper and resonator the correct thing to do if I just want a slight sound upgrade? Thanks guys!

Which Headers do you recommend for a truck equipped with the 6.2 liter L86 engine? 1.Which ones do you have? 2. Why do you endorse them? -Cost -Quality -Ease of installation -Size (1 3/4 Vs. 1 7/8) -Performance -Sound (tone quality, volume, drone) -Longevity -Value (cost, complications and effort Vs. added performance and enjoyment -Downsides 3. Associated exhaust parts 4. Any other special considerations i have a 2015 High Country 4WD 1500 CCSB with the 6.2. I have decided to possibly “tune it up”. If it is financially feasible and will add to the daily driving enjoyment of this truck. It is not a “pig” by any means, but it lags a bit, especially with the larger/heavier tires and their effect on gearing. I think it would be greatly improved by being “woken up” through a few steps. I am considering: Banks CAI Ported/Polished stock throttle body BlackBear Tuning 194* GM Thermostat and slightly more aggressive fan profile in tuning. LongTube Headers with Cats Dual Exhaust Mufflers and Resonators - I have had good luck with and like AERO Turbine mufflers out of Utah. I was considering two of his AT3030 mufflers and two of the AR30 resonators, somewhere over the axles, with L/R tips behind the rear wheels. In looking at my plans, I think that the exhaust without mods would be a bottleneck. I currently have removed the factory muffler and flapper and put back an Aero turbine 3030XL or maybe 3535XL muffler. (I don’t remember) What at do you think of my plan? What is good or bad? Help me decide what to do. Headers and a full exhaust change can become quite expensive, if the gains aren’t that significant, maybe this part of “the plan” can be changed. If you feel that headers are not needed, please share. Please try to be clear, concise and factual in regards to your Header choices. Let’s not get too derailed discussing just mufflers. Hopefully this thread can help many others with this particular decision. I searched the exhaust thread, but it is daunting to find this particular information. Thank you for sharing your wealth of knowledge and experience. The members here make this forum the best of its kind for our trucks. -Darksky -
Turns out the Rebel TRX concept is heading to production very soon. Has anyone seen this new unveil from Ram? Been waiting for a performance truck from GM for almost 2 decades now. Not a street unit, but apparently this beast will have options for a 575hp 7.0L NA Hemi, or the supercharged 6.1L Hemi making 707hp as found in the Hellcat and Trackhawk. I never thought I would consider a Dodge, but this thing puts the Raptor and anything GM makes to shame in the truck department. https://www.ramtrucks.com/en/limited-editions/ram-1500/rebel-trx/ https://www.caranddriver.com/features/the-2018-ram-rebel-is-a-car-worth-waiting-for-feature What do you guys think? -
I just bought my first newish truck, being the 2014 Silverado 2wd z71 lt. It’s got the crew cab with 5.3l under the hood. I’m currently stationed at ft Stewart ga. Im just looking for some help or some advice on some upgrades I’d like to do to this truck and which products might be the best. - I’d like to change the headlights and fog lights from stock. - Put a leveling kit and some new (bigger) a/t tires on it and not sure what size being 2wd. - Change to an aftermarket air intake. - Do something about the shitty stock speakers (without Bose). Wether it be new door speakers and sub(s). Or be just subs and have a separate amp just for door speakers. Do I need a processor to hook up to stock 8” head unit. - How do I add any app or navigation to this stock 8” head unit - Exhaust? - How to get more performance from the truck. Anything would help, Thanks

Hey everyone, as the title says; I’m looking for your advice/input on an exhaust and tuner set-up. I have the AirAid MIT and K&N filter installed on a leveled 2016 Sierra with the 5.3L V8. Muffler: I was originally planning on installing the Flowmaster Super 40 single in/dual out, but I’m reading mixed reviews. I want to notice the exhaust, but I do not want to be annoyed by it as it is our “family” vehicle at the moment. I like the refined deep growl way more than an obnoxious cackling. What comparable mufflers are out there around the same price as the FM S40(~$110) with possibly better performance and a more refined sound? Tubing: Which is better sound/performance wise? Would a single muffler with 3” in/3” tubing to 4” tips sound more refined as opposed to a single muffler 3” in/dual 2.5” tubing out to 4” tips? I will be removing the resonator. Tuner: My truck has the infamous throttle lag/fish bite/etc. where it always seems to be in too high of a gear then makes a hard downshift. I am looking into a tuner to modify the shift points and firmness, as well possibly turn off the AFM above a certain speed if the V4 drone becomes too annoying. I am also planning on purchasing new tires a little larger than stock in the future, so being able to adjust the speedometer for tire size will be required. Right now, the cheapest option to accomplish this is the $200 TruXP Xtune Plus from Auto Anything. From what I’ve read, it is basically just a re-branded Superchips Flashpaq F5/EdgeEVO HT2. Is there anything wrong with this particular tuner and its “canned” economy/87/91 tunes? Can I still customize the shift points/firmness and throttle response outside of those tune?

Has anyone taken off the plastic from under the front bumper? I'm debating a leveling kit, but really I just want a little more clearance in the front for now. If you've taken it off, has it affected the ride or mileage? I know i'm being paranoid here, but it IS a brand new truck. Want to take care of it. I talked to a service guy at the dealership and he said it's strictly cosmetic. Anyone know if that's true? Any feedback would be great. -
Cold start and idle of my Corsa Sport on the Avy. Sounds incredible under load and WOT and very quiet in the cabin when just driving regularly. Definitely wife approved (and that counts for a lot LOL). Hope you enjoy

I'm new to this site today. Anybody on this forum have any experience with the slp level 2 kit? It contains a sealed cold air intake ,slp cat back exhaust- rigid no mesh which I don't like - and a slp tuner for the cold air intake and exhaust maximum utilization. I currently own a 2016 GMC 1500 Denali p/u with the 5.3 8 speed auto. This a spare vehicle we got at an amazing deal with 2k on it. I'm looking to maximize the potential of the 5.3 without sacrificing efficiency. I was told by a slp rep the "tuner" that comes with the kit is dyno with 87 octane. I like my truck but it can run a lot smoother. Thanks everyone

I just ordered a Bully Dog Platinum GT Tuner and have heard some good things about it, for an 08 Silverado 1500, with a 5.3 what gains in horsepower and torque should i be getting and how noticeable will it be? Also what will my fuel economy be like with the tuner all on performance settings (right now I get about 14 on 32's?
