I am working on a 2001 Corvette. I tried to increse fuel by 3% and left everything else the same from the stock tune. I flashed the PCM and went to go for a run and it went into reduced power mode. There is no check engine light or anything like that. I went into the table C6101 which is the expected airflow table and incresed all the values by 10%. Same thing. Went back in a did another 10% with still the same results. I have the tune file and the log file if anyone wants me to post it up. Just for info this car has a Weiand Intake manifold, K&N intake kit, exhaust etc... They are changes that would mean an increase in airflow but nothing major like heads or cams, etc... Any help would be greatly appreciated
