    Okay so I have a 2008 Grand Prix which, for some reason, isn't compatible with HP Tuners. To get around this I sapped out my 2008 PCU with one from a 2006 but even since I did the scanner is reading really low fuel trims when I'm at or near idle and I don't know why. I can't figure out for the life of me what is different between the 2006 and 2008 that would cause this??? Please help!
