Well it's time to make a decision on camshafts. VVT or not is the question.
BTR has several cams I would be happy with as does Summit in their Pro Ls line. For those that have deleted the vvt, did you have it tuned before you started it? Did you notice any difference without the VVT?
There are 2 schools of thought on this and both are equally valid.
@iamdub will rightly tell you that keeping VVT is worth it because it preserves more on the low end. It’s like a free lunch.
I will tell you that I deleted VVT in my 2012 with the 6.2 and selected a 3-bolt stage 2 truck cam from cam motion designed specifically for the 6.2. I tow a 7000 lb camper with it and picked up considerable performance in the mid range which is what I needed for pulling up the hills. I went from having to wind it out at 40-45 in 2nd gear to holding 55-60 in 3rd up the same grades, no problem. It’s also subjectively more responsive and powerful on the low end than my ‘07 which also has the 6.2 but still has the stock cam, so I get to drive them back to back often. I wanted simplicity and durability and didn’t want to mess with cam phasing and all of that.
I’m happy with my choice, though I often do wonder what I'm missing that I'd now have if I'd kept the VVT. The guys who kept it say they're glad they did, and I can't argue with that. And those who did the work themselves say that working with the VVT is nothing to be intimidated by. So there's that.
I used black bear for the tune and they sent me a canned tune ahead of time that I could use to get up and running with the new cam, and then I did the data logging with their Autocal and they sent me back some tweaks to get it dialed in right.
