Well, from your first post, it sounded like the symptoms started after the incident with the aftermarket remote start. Or did they start right after installation of the new exhaust? I guess the best thing you can do is take it back to your tuner and put it on a wideband and see what's going on in there. Maybe there's something in the remote starter that is messing with fuel trims? Not sure.
