I have a few items I'm selling to make some room in the garage. These items fit a 2014+ GM 6.2L V8. If you happen to live in New England I can possibly come to you.
This is why I'm selling the parts. Had the truck for a few months and a handful of lifters and pushrods S.T.B.. So I went down the rabbit hole :).

I purchased and installed the Cold Air Intake for my 2019 GMC AT4 w/6.2L. Had to have dealership "Reflash" computer. They weren't supposed to charge, but they did. Haven't gotten anyone to call me back to explain. (Milford, CT Chevrolet/GMC).
I drive hard and fast. I'm only getting 12-14mpg! 15.5 best hwy during 3k mile trek from WA state to CT. I know have 4,700mi. Put air intake after I got to CT. I have stock 20" w/All Terrain Goodyears.
I'm looking to put a cab high bed topper on this Dark Sky Metallic truck. Any ideas?
I'd like to level it like I did my 2018 LTZ, but with it already has a 2" lift, and I'm not sure who can do it or supply me with the parts?
Lastly, Why The Heck does Chevy/GMC Trucks not have a locking gas cap?!?! My 2015 C7 Vette does! With Proximity sensor push to open!!! $70k and no locking gas cap. I don't care about gas thieves. I care about gas tank vandals!!!!
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?

So back in a GM truck since the 2003 YukieXL got adopted in 2012. Got the SRado and 19 mpg around town after the generic (folks dog em out so I been going with knockoffs and with CAD today they’re pretty good. Truck doesn’t know.) makes the AFm not as noticeable and seriously 19 mpg in a truck combined . Never got better than 13.9 in my 5.7 Ram. Gonna go with cat back next...maybe tune.
Read every post before I attempted to get into bed through firewall to continue the Audio upgrade. My link has possibilities...AppleCare play upgrade or the Alpine head swap if budget ever can handle. Going through the big grommet is too much work guys so the little grommet under the drivers door hinge...15 minutes and pull the grommet back in the hole a snap. I got some pics so hope the show. Went with a BBox down firing dual 10 box. Only issue is where to mount the Amp and audiocontrol LC2i . Raising seat or on back wall seems intensive unless using expensive Alpine bass kit but little room unless front of box. Better weather would motivate me to pull back seat out and build a suspension mount like Alpine does. Trying to use set up from previous sled...save some dough. It’s DablueSmooth now but forgot my new password so musical names for next 30 days. Pictures are too big or failing to load from the iPad ...I’ll post from phone
