  1. EcoTec 6.2L V8
    My 2015 GMC sierra has a misfire on cylinder 8. We narrowed it down to a worn cam lobe. We mesured each rocker and found a .13 difference on cylinder 8 than other rockers. How hard is it to replace a camshaft? I know all lifters would need replaced as well. I'm considering the delete. The...
  2. Exhaust
    To me the corsa for the 6.2 doesn't do it justice, the borla touring is a joke, the sport isn't enough after a cold start and the atak is too much all the time. The AWE is perfect!! Here's a video if yall want to check it out
  3. Exhaust
    Hello, I have a 2021 6.2 Chevy Silverado, and I just did a muffler and flapper delete. Sounds amazing but is way too loud on the highway and drones too much for me. I am wanting to put a muffler back on but I want one that is as loud as I can get with no drone. I was looking at the Flowmaster 50...
  4. Vortec 4800 4.8L V8
    I have an 08 Silverado 4.8L with about 480,000 miles on the engine. I have recently come across the chance to swap in a 2012 Camaro ss 6.2L with 54,000 miles on it. I was wondering how difficult the swap would be and what all I would need to do.
  5. Engine
    I own a 2015 GMC Sierra. I posted another forum but I didn’t get many answers so I’m gonna try this again. My truck is misfiring on cylinder 8. My check engine light will flash and my Stabilitrak light will come on. It does it really bad at idle. Very rarely will to do it when I’m driving. It...
  6. 8-Speed Automatic Transmission
    I bought my 2018 Silverado 6.2l LTZ brand new. I didn't know of these issues with the 8 speed transmissions at the time otherwise I probably would have just went with the 5.3. Anyway, I've never experienced the shudder, only thing my transmission does do is when it's cold out and the truck is...
  7. Exhaust
    Long story short, my wife has been driving my '18 silverado ltz dbl 6.2L for the past 18 months or so and I just got her back. I have a k&n cold air intake, diablo tune, but a cheap exhaust. I'm not sure what it is, all I know is a muffler shop did it for $250 and it sounds great but I'm sure...
  8. EcoTec 6.2L V8
    Hello, I'm new to the forum and hoping you can help with an issue. Sorry if this is a little long winded but I'm trying to make sure I get all the info in here. My 2018 Silverado 6.2 has been giving me a intermittent check engine light that I had read as P015D, HO2S delayed response lean to...
  9. EcoTec 6.2L V8
    When accelerating between 1200 and 2k at speeds higher than 60kmph, i get an inconsistent rubbing noise and vibration that sounds and feels like its coming from the drivers side tires/wheels. As soon as I take my foot off the gas the noise stops. Just bought the truck (6.2L 2014 Silverado Lt...
