Car is currently running 21psi on a KB2.2 Gen 1. Looking to get out of the ragged edge right now, can I drop it down to 19psi (or whatever is recommended) without the car running hella rich? Would I need to have the car re-tuned?
who tuned your car?
Curious because my car came from the midwest as well, and was on 22 lbs on pump gas......and someone thought that was ok....
