So I recently put the GM stage 2 on with a ZZP heat exchanger and took it to the dealership to get it reflashed. when I got it back i noticed when im on the highway when I romp on it the car seems to putter until i let off the gas... i got no CEL and im reading lean with p0172....i dont know what my ATF ratio is right now but it just seems when it goes off the line it just trips and eats ****......Mods done engine wise are GM stage 2, AEM Cai, Pacesetter header with borla muffler, zzp heat exchanger

Sounds like they flashed the wrong file on there, I wouldn't be boosting at all. Go back to them and ask about it.

you know what i kinda figured that becuase when i brought it to them to get reflashed they had no idea what i was talking about i had to like tell them it had to be recalibrated and the packet with the authorization code was in the car and they looked at me funny
