new to the efi tuning game. getting beat up by a 2014 camaro on what should be simple maf tune. when i make a change it overshoots by sometimes 20%. it seems like i have a decimal off or something. trying to do copy paste by special percent-half seems to do same thing. i feel like i am doing something very wrong or setup is wrong. i have re done their cheap cold air intake so it has 8 inches straight before maf, new solid elbow, new gm maf sensor. this car came to me not running bought from auction with supposedly on 22k miles. it cleary has a junkyard hi mileage engine it it. looks as if by all the other mods it had something a way more than stock in it and by all the oil everywhere it came apart.
