Does anybody have an 03-05 Cavi/Fire with the 2.2 ECO that has used HPTuners? I have an automatic and I am trying so hard to find a good tune. I have been messing with shift points but i cant get them down. Im making 136whp and 138wtq and still only hit a 16.00s at 86mph. How much timing can this motor handle running on premium gas? Any help with this car would greatly appreciated since I have gottan little to no assistance on the HPTuners forum.

Timing really depends on the motor. How much Knock are you getting?

Have you read any of Shifted's sticky's on J-body?
