Stock 2011 Lean issue
I have a 2011 GT, all stock minus X pipe. Having an issue where it's really lean during tip-in and needing about 20% higher MAF values than stock in medium to high load. I'm coming over from the ecoboost stuff from Cobb, so this isn't anything crazy for me. I've smoke tested it a couple times, found some small leaks and fixed them. Reset KAM and it's on the factory tune. Fuel pressure is also in spec. Am I missing something blatantly obvious? Or are the factory tunes really that bad... The car is pretty un-driveable like it is. It had a previous tune from another shop with the higher MAF values, which doesn't seem right. Car runs a little better like that, but not much.
