I never wanted to be that guy, the one that just wings it when learning something new, but here we are.
Anyway.. I need help with getting it running in a richer direction, and now I'm way over my head I feel.
2008 GMC Yukon 6.2 AWD. The 6.2 started making a noise and upon changing the oil found it had made glitter. Not wanting to spend the money on a Junkyard 6.2 I opted for the cheaper 5.3. I've done the following "upgrades" (might still be a net loss here, but whatever. ) The truck was running good before I did the exhaust, but I wasn't happy with the performance out of it. I've been slowly tuning it down to being a drivable vehicle, it still has some hesitation at all throttle inputs and especially when cruising. Most recently it has been going extremely lean, 23+.
