Cobb has had OTS maps for the AEM CAI since MY '08.
OP, you have verified that the rev limiter isn't involved?
Also that the MAF sensor isn't in "backwards?" Happens.
Does it idle OK?
You're right about suspecting the injectors. When replacing your plugs they will give a clue. Lots of cars from that area of the US use E85, thus big injectors. If it ran OK when you got it someone had put an OS tune on it and no Cobb OTS map will work. If the plugs are black that would be a clue. Is there any indication the injectors have been replaced? Like missing brackets, etc?
IF they are big injectors you can still use Cobb maps... you'll just have to set up the injectors with ATR. Logs would be good.
