Runs great with the tune. You should really think about camming that 6.2L and you would be surprised at the outcome, unless you are worried about keeping the warranty.

 

Not to worried about the warranty, I know the guys at the GMC dealership pretty well and unless I go really crazy they will work with me. I have been working with AKlowriderZ71 and we have some plans for it. First and foremost is getting a wideband and a getting that tune really dialed in, second is a stall...probably a Yank.

I would love to put a nice cam in it and get rid of the VVT but I also heard that if I ever get a Procharger I should match my cam with that. Procharger is a ways down the road so I might just save up for the cam and see how much I can get out of this 6.2 NA

 

Yeah that wouldn't be a problem on the cam. You can get a custom spec cam for the procharger and just run your truck NA until you save up for the procharger. Procharger recommends a 10 degree higher difference on the exhaust side of the cam vs the intake. Anywhere from 6-10 degree difference would be fine though. Yeah I would prob do the stall first also, but make sure it will match good with your goals so you don't end up having to change it out again later on.
