so recently ive been having problems with my 2008 cobalt ss, everything points to my ecu going bad so i started looking for another ecu and found one for sale not too far from me, its a zzp ecu thats tuned for 25 psi, it was on a car that had full bolt ons. Im just wondering if i buy it and plug it onto my car that only has an injen CAI and muffler delete if itll be good, i know it couldnt possibly be perfect but will the stock MAF be able to work properly at 25 psi? And how will the fact that im not full bolt on and mostly stock exhaust affect the tune?
