Hew everyone I'm new to the forum and just picked up a 2014 crew cab LT yesterday and I was wondering if anyone has modded or installed any performance upgrades to a v6 and maybe what's available I've searched but haven't found anything

I haven't seen much talk of modding the v6 except for intake / exhaust on these forums. First mod for most would be the $1095 option for the 5.3, as the v6 was really meant to be the lighter duty eco option for these trucks. What goals did you have in mind? Towing, speed, economy?

The K&N cold air intake kit made a difference in my trucks performance.

Intakes sound cool but, rarely add any appreciable performance  unless paired with a decent exhaust... Not much you can do except exhaust, intake and a tune.... Honestly having had both motors, under day to day driving there isn't much difference in the two unloaded...

285 hp. stock from 262 cubic inches. Pretty stout already. E-85 will take it to 305 hp. if you can find REAL E-85 but cost you about 30% in mileage. Intake and exhaust will get maybe 15 or 20 more with a tune. Expensive in cost per hp. None of that will be noticeable on a day to day basis except for the noise and the hole in your wallet.  

 

Back in the day you could sometimes get both economy and power from a motor with carful choices but today its not unheard of but difficult as economy and power in a modern motor lean against opposite walls.

 

If your serious about the feel of power and don't mind a loss of economy think gearing. It isn't cheap and will require an outside tune of anything deeper than 3.42 but a 4.10 will wake the dead.

 

Yea, I'm pretty much with Imcrazy on this one. Don't worry … be happy.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      By SteveP45 · Posted

      Idler Pulley… from what I understand GM and Chevy trucks no longer have an idler pulley.. they stretch belts for both belts… I had mine replaced by my local mechanic last year on my Chevy Silverado 5.3 z71 LT.   They have discontinued using them on 2019 through 2026 as of a Google search.

      Whirring when accelerating at 1100 rpms 2022 LTZ 5.3

      Good morning! I have a whirring sound coming from the engine or transmission area when driving w/o towing when I accelerate at 1100 rpm’s. That’s how it started. Yesterday it was more obvious while towing a U-Haul even when not accelerating at 70 mph. I could see where it may have been possibly shifting gears due to a slight grade and the intermittent rpm changes as the transmission was possibly lowering the gear down. It was making the sound multiple times but it is not constant. I replaced the serpentine belt and idler pulley but no change. It only does it when I’m driving. No noise accelerating while in park. Just started @ 53,000 miles. It’s not always there though. Unfortunately, I feel it may be transmission related. Any thoughts or knowledge about the 2022 tranny that anyone can share. I have 2500 miles left on my p-train warranty. Thanks to all for any help!

      RAIN. It's dumping buckets. We needed it. What a welcome change...sitting here listening to it pour with my office window open.   Ok, not too much. It's not even September yet, we're not finished with summer yet....

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      If you have actually done it, there must be some secret tool or method of accessing the hidden bolt head that both manifold connections have. Two of the three bolt heads are staring at you in the face from below but the third one is covered by shielding and as far as I know only accessed by removing part of the fender well lining to gain access to it and even then its awful to access or from what I had seen of someone fighting with it on a video.    There is a reason why even mechanics that deal with the awkward or risky business of undoing the exhaust at the manifolds have done the same method others are doing with these L8T by flexing the exhaust if need be or just able to slip the pan out as I did without needing to touch hardware or pry on the exhaust. By rights the two seals should be replace when those joints are cracked loose as well.

      Actually it was a lot more controlled then I thought it might be and that isn't actually when I spilled some oil. I had thought prior of rounding up a couple of longer bolts with the same thread to swap out for a couple of the front edge pan bolts and then leaving one bolt left in the back but loosened off and then using a suction device to remove most of the fluid, that certainly would have worked and while I do have a couple of different devices I could have used to suck the fluid, now having done the job once I wouldn't even bother. I had thought of buying one of those pressurized vessels to suck or new fluid in and would if I was doing a job like this on a few vehicles but with one vehicle I just didn't bother and I have pail pumps as well I could have used assuming the hose end would fit into that less than roomy space but being such a thin fluid it pumped well with a quart type pump and just kept the hose into the trans and kept swapping containers and repeat.    What I would change to the method I did though was first jack up just the rear of the truck to put on jack stands to allow more oil to come out of the check plug on the front of the pan ( and as I did, I made sure to put that drain plug back in finger tight ) then follow through by putting the front on jack stands. Also that I would have used a larger sized drain pan in the sense of covering an area wider/longer beyond the transmission but I didn't have one and saw someone else on a youtube video using a masonry mud mixing tub and bought one at a hardware store to use in the future. The main oopsy  I did and why I spilled some oil was all my fault as I neglected to follow my own plan, I should have let down the pan as I did to drain out the front of it as much as would come out but then scooped out the remainder of the oil with the Dixie cup I had sitting there just for that purpose as by that point there is enough room to reach right into the front of the pan and just bail it out basically.
