i just got my car back from the dealership they replace my trans cuz it spun the output shaft bearing.
so the next day i put my boost controler back on took it for a drive and it threw 3 codes. one was iac reading worng. barometric pressure somthing or other and multiple engine misfire. wtf?

it might be because i unhooked the map when installing it and the key was on . but i dodnt start the car till it was hooked up again . anyone think it could be from this.

btw i cleared the codes and put like 100 mile on it since with no problems
