  1. Up for sale is my DiabloSport inTune i2 I2030. This tuner will come with 3 unlocked GM licenses for you to use (I understand it shows 2 available in the picture but the 3rd will be unlocked this week and will be validated before shipment). Works perfectly fine and is completely up to date. With 3 licenses, you can tune your truck and just sell it without losing a dime. Picked up a 2019 and don't have a use for this anymore. Please don't hit me with lowball offers. Each GM license is $100 alone so take that into consideration. If you only need a single license then use it and sell it to a buddy, or charge him for a tune. Price is $300 shipped to contiguous US.
  2. 4.11 gears

    Hello, I got a question about re gearing from 3.42 to 4.11. is it necessary to get the tune/ speedometer calibrated ? My truck 2018 Z71 5.3 6speed 3.42 gears. I got a 8" lift with 35 /12.5/20. The actual tire measures 34.5 x 13.25. I don't want to void the factory warranty by plugging in a tuner if possible but I would hate to cause more damage by not tuning also. Thanks
  3. Thinking about doing an intake, exhaust, and tune to my new-to-me 2017 Sierra 1500 5.3L 8 speed. I miss the throttle response my 2013 6.2L had, it would lurch forward at the slightest tap of the gas. I also want to hear the engine, its so quiet! Cold air intakes seem to be disputed for having any performance gains, so are they really worth the $$$ in terms of better air flow? healthier engine? sound? any words of wisdom? Your $0.02 is always appreciated! I'm looking at the Magnaflow 15267 catback as it seems to sound pretty good for what I'm going for. I've read that there is a flap in the factory exhaust system that creates back pressure for AFM shift into V4 mode. I do like V4 mode and would not want to go away with it. How can a catback system integrate this feature? Also, what would be the rough performance improvements if any from a catback exhaust? Any other options that would sound similar and perform better/keep V4 mode for around the same price as Mgnaflow (~$800)? As for the tune, I know ZERO about tuning but do want to get rid of the rev limiter, speed limiter, get some performance gains without having to put midgrade or premium fuel in. How does the tuning process work? about how much do they cost? how can it be adjusted in the future? I assume anything like this would void some sort of warranty? Anyone do something similar and can attest to their experience with an intake, tune, exhaust?
  4. Truck details Make/Model: GMC Sierra Year: 2014 Engine: 5.3L L83 Trim: Work truck (blue blood truck right here) Transmission: 6-speed w/ 4 wheel drive Gears: 3.42 Miles on truck: ~53k Miles driven on tune: ~3k Performance Mods: None, apart from the tune of course Other mods: bed cover, remote start, tailgate damper Tuner: Diablo Intune I2 Truck role: Getting to/from work and doing work. Have another car for long trips Background I purchased a Diablosport Intune I2 for my previous vehicle, 08 Colorado I5. The tuner for that truck was the best investment I ever made, especially for the transmission tune. Lightning-quick shifts, more power, better throttle response, no complaints. That truck has since left my life, needed something with more payload, in comes the Sierra... Intro The truck commutes 15 miles per day for work and is otherwise a weekend warrior. About 80% city, 20% highway driving. Had no complaints with how the truck drove, until I started noticing an occasional downshift "clunk" when going around corners between 20-30 mph. Then, I remembered how awesome the I2 made my Colorado transmission. Said, "Screw it, lets tune this thing and see if the problem goes away." So I purchase the extra license for my i2, install the canned 87 octane/firm shift tunes, and go out for a drive... Big mistake. The canned transmission tune was QUITE bad. Started investigating, lots of complaints on the Diablosport forums, only solution is to try a Diablew tune. So, $150 and 3k miles later, here we are! The Process Contact Diablew with your information, wait 5 seconds for him to respond, pay the man, follow the instructions, profit (for him... and you, eventually). Don't want to cover this too much as it's not that interesting. Onto the tune! The Tune One engine and one transmission tune provided with tweaks available upon request. The engine tune can be provided for the octane of your choice, but keep in mind that the 87 and 89 octane tunes are the same with no spark advance provided for 89 (ie. might as well run 87 unless you tow in high temps, or just request the 91+ tune). The engine tune, after driving 150-ish miles... wow, I like it. Noticeable power increase in the low end (around 1.5k rpms). Feels better across the board. On the stock tune, I was getting random blips of knock retard on mobil gas, even 89 octane. The Diablew engine tune has yet to register ANY knock retard on 87 mobil. Better for the engine, more power, can't complain. The V4 mode was also disabled, though I did not have an issue with V4 (part of the "Cannot notice it's even working" club, which only has 7 or so members on this forum). MPGs are about the same, pedal feel is spot-on, spins the tires too easily (not a complaint, unless its raining) The transmission tune, on the other hand... it's not bad, but not for me. This was the primary reason why I wanted to tune in the first place, but I am a bit disappointed as a transmission tune made my Colorado (by comparison) FAR better than stock. The tuned transmission on this truck shifts a tad later (which I felt wasn't necessary) and also *tries* to shift firmer. I say "tries" because the firmness is random. When the transmission tune shifts firmly across all gears, I love it. But, the inconsistency breaks it for me. It also does NOT shift faster than stock, or at least not noticeably so. After searching through tune forum posts for this truck, it seems like everyone has had a different experience and probably no fault to Lew as a tuner, just that the truck has a silly transmission. No improvements after 3k miles of driving on this transmission tune, either. Remember that downshift clunk when taking turns around 20-30 mph? Since the transmission now shifts harder, the flaws are more pronounced. I reverted back to stock and due to the additional engine power in the low end, I think it makes the stock tune that much better. Due to the higher shift points, I feel that this tune would make more sense for a truck with the 3.08 gears (vs. my 3.42) as many people with 3.08's seem to hate the shift points. The tune is worth a shot no matter what, but my truck did not like it, unfortunately. I gave the Diablew TCM tune another shot. After the paint-stick-gas-pedal mod, this tune has definitely improved. Lew says its the adaptive transmission just doing its thing (more the reason to shove something up behind that gas pedal, the truck just performs better all around). The upshifts are much better, driveability all around is "as it should be" and the shift speed is definitely better than stock. Shifts fast and smooth. The only complaint I had was with the downshifting. When approaching a stoplight, the truck felt like it had a less-aggressive engine brake, causing me and my passengers to lunge forward. After asking Lew to modify the downshifts to be less-aggressive, I loaded the new TCM tune and all is well. I have changed my review to reflect that the TCM tune takes some time to adjust, but combined with the gas pedal mod, its totally worth it. Just be wary of how your truck behaves on the downshifts and notify Lew accordingly. Final thoughts Want more power for only a few hundred clams? Get a Diablewtune. More power than the canned tunes, less knock retard, and will take advantage of engine mods. Certainly try the transmission tune as "your mileage may vary" (har har), but the engine tune alone was worth it. Estimated gains from Lew are 12-39 HP, 10-35 lb-ft of torque, and +0-3 mpgs (all of which are mod dependent). Since I have no mods, I am happy with an additional 12HP/10lb-ft. Feel free to ask any questions!

  6. I think I've narrowed my tuner purchase down to one of these two options. What do you guys think and why? Got a better option? I'm all ears.
  7. Ok first I want to apologise if this thread has been done. I just started my account today. So I bought a 2016 Silverado 1500 LT Z71 4x4 with 37k miles a few days ago. It has a 5 or 6 in RC lift and 35x12.50r20 MasterCraft courser MXT tires on it. And the Hostile predator wheels. My question is, I don't know if the truck has been geared. Tuned. Or calibrated by the previous owner. The dealership doesn't know. The truck doesn't feel "sluggish" to me personally. I drive past the digital speed trap in my town and if I'm doing 30 on my guages the reader says 31-32... On the highway at 70mph my tach reads the notch under 2k.. so 1800?.. when cruising at 30-35 my tach reads around 1100-1200. I find I get in town with A LOT of stopping and going around 13mpg and that's driving very conscious. I notice it shifts around 2500 and then lower in the higher gears like 2000 then 1500.. but seems to chug along nicely around that 1200 mark. Also. My V4 mode has never turned on once. Not sure if that's due to the current cold northern Ohio climate right now. Or if the previous owner has a tune on it and disabled that feature. I just don't want to spend the money on a tune and calibration if I don't have to. When I floor it it gets up and goes fast imo. I don't floor it often at all. It doesn't pull or tow or haul much. I'm a maintenance engineer in a flat Ohio town of 50k ppl. So I don't think I'll regear because it won't be working too hard. If I could get some folks to shed some light on my curiosity I would greatly appreciate it. If all else fails. I'm buying a good tuner I guess... Thanks guys.
  8. transmission failed in my Silverado the other day at 103k, bought a used one with 32k miles and I am swapping it here at the house. I know I would need to re flash a reman transmission but what about a used one that came out of the same vehicle?

  10. Just bought an Edelbrock supercharger for my 2014 5.3 with out the Edelbrock tuner. Got an unreal deal of 4500 for it!!! Couldn't pass it up!! I search and couldn't find much information on getting a reputable tune other than black bear. Just wondering if anyone has a reputable shop in South Florida or a shop that uses HPtuners that would be good over email.

  12. My 2014 Sierra 6.2 has 36k on it. Occasionally when I floor it going from the 1 to 2 shift and 2 to 3 it will make a backfiring noise and puffs a little dark smoke. Has anyone else heard of this issue or have any idea what would cause it? It's weird because it seems to come and go. It's stock tune with an airaid intake and gm Borla exhaust. I didn't notice it was doing it until I put the exhaust on. I've been considering a black bear tune and thinking that may help if it's a tune issue .
  13. Recently purchased my first 2500 and opted for the gas burner option instead of diesel " to hard on my pocket" Looking at options to have options of attempt to save gas and also swap to unload the mustard when need be. What options would you use or have installed and what you like or dis-like about the tuner?

  15. I'm going to be lifting (w/ 35s) my 14 sierra 5.3 ccrb. I would like some input/ advise/opinions/experience on cai, headers, exhaust and a tune, to make up for power loss from the lift. I have a 3.42 gears. Thank you.
  16. 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!
  17. I was wondering what the differences were between the Intune and the Predator2? Anyone have experience with both or know the difference? Doesn't really say much on the website. Difference is about $50 in price, with the Intune being more. I assume the Intune has more features, but looking for real life examples and reviews. Any help and insight is appreciated.

  18. I fell down the rabbit hole it all started with an AirRiad full intake and then I got to thinking. I need a cat-back exhaust, headers and a tune. Here is where I am at. -Borla touring dual exit - http://www.gmperformancemotor.com/parts/19303342.html -AirRaid full kit - https://www.airaid.com/search/product.aspx?prod=AIR-203-111 -American Racing 1 7/8 headers and high flow cats - https://americanracingheaders.com/collections/gm-truck/products/gm-truck-6-2l-2014-up-long-system?variant=29943904900 -Efilive flashscan V2 from Blackbear with email tune - http://store.blackbearperformance.com/EFILive-V2-Scan-and-Tune-GM_p_17.html I ordered everything but the headers I have a local shop that I feel comfortable having install headers https://www.eastcoastsupercharging.com/ and if they are installing them I will just let them order them for courtesy. They work on mostly corvettes and camaros also trucks. My only concern is the cost and I am curious as to what you guys think about two things and some help with my decision. -should I have them purchase and install the headers and "street tune" for $3149? keep in mind they are also installing the cat-back Borla exhaust which I am supplying. So $3149-$1775=$1399. minus the cost of the headers it is $1399 for the header and cat-back install and street tune. -OR find another installer that I trust to do the headers and cat back install and just use Blackbear for the tune that is included with my flashscan V2. I like the idea of having two different tunes so I can compare and see which one I like better and get to learn efilive and hopefully do some of my own tuning in the future. Please no comments why don't you install everything yourself. I did the intake and would have no problem installing that cat back but headers are out of my league. Thanks just wanted to bounce this off of you guys and see what you all thought.

  20. AFM-Mods

    Hello, I had a couple of questions. First When i go to autozone.com and enter my vehicle there is two options for the 5.3 (7) or (0) What are the differences between the two? I have the (7) in my vin but I'm still not really sure what the differences are between the two engine codes. If there actually is a difference in performance or internal parts? Next, What are everyone's thoughts on disabling AFM my thought is its robbing me of some horse power and throttle response. I know i can get a tune to disable it but i wasn't sure about the pros and cons of that. I have heard after a while the engine will start eating oil because of AFM. I only have 84000 but still. I was also looking at getting a CAI between K&N and Volant I was leaning more towards Volant because of the closed intake box not sure if it has that much of difference but, i live in az and its dusty and when it gets muddy i don't want engine to be sucking up that water with the intake. I know the intake is not going to give me substantial amount of Hp or torque. The engine seems to breath better i have a friend with same truck and has K&N and it sounds really healthy and throaty. Pros cons on each? I have flowmaster super44 and love it I think that if i had an intake it would just sound even better. With that i was wondering for as cheap as it is with throttle body spacer if any one has really noticed a difference. Lastly seems like Diablotune is the way to go any other tuners that maybe a little cheaper that does all the same stuff? Thank you in advance Jordan

  22. 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?
  23. Got rid of my 2014 Silverado, So im selling my DiabloSport inTune I-1000 tuner. It has been unmarried, as you can see in the 4th picture. Comes with original box, paperwork, and cords. Like new condition. Asking $225 shipped priority mail within the continental US. Payment via PayPal Goods
  24. I have recently installed a K&N 71 series blackhawk intake with an airaid throttle body spacer on my 08 silverado 1500, there are no vacuum leaks and my check engine is on. Could this be from my 02 senor not used to the high flow and not reading right? I also have a magnaflow catback system and was wondering what i should do to fix this problem, ive been told a bung spacer could take the CEL away but wont run optimal and a tune would be the best for my truck so my ecu would recognize all of the new flow going on.
  25. I Purchased my 2015 silverado z71 crew cab a couple months ago, so far i love the truck accept for one issue that shows itself every once in a while. USUALLY while turning and acceleration lightly at the same time ( lugging the motor pretty much) ill get a very noticable shudder right before the truck FINALLY decides to downshift. Has anyone had a similar issue. Im going to drives my buddies sierra tomorrow and see if i get the same shudder. I have 3600 miles on this truck so i dont think its anything to do with the "adaptive" transmission learning cycle. Ive heard a custom tune can resolve issues but i really hate to do that on this new of a truck, nor do i have anywhere within 400 miles to get it done. New to the forum guys, hope to get some responses, this is my first GM product. Switched from a 2008 tundra with 245000 trouble free miles. Hope i dont regret this purchase
