Have you had the car tuned? You'll need a custom chip now that you've stepped up to 42's.

I think he meant the ECT. Engine coolant temp sensor for the ecm. Unless there is a real problem, not much until you get it tuned. Have you checked for codes yet. You have the correct mass air calibration for those injectors?
