check your 02 sensor make sure its toggling.

Ill check the 02, soon as i figure out how lol

it has a fresh tune up on it, motor only has 3k, and my right foot is light these days lol

 

Easiest way, is with a data logger or dsmlink ect..

O2 and FPR are the likely causes.
FPR will cause it to run incredibly rich at idle then lean under boost.
Did you ever fix the described single injector issue?!? This could be causing a problem, the other 3 could be dumping fuel to compensate...

 

Yes i fixed the issue, i replaced all 4 of the wrong injectors with the correct 5 speed AWD ones
