this is when i went to spi (2 hours of tuning $$$)
I cranked it up to +40% at 5k rpm where it was ~13:1 to see if it would bring it down, it didn't really help much. At 6k rpm I'm taking out 14% and am at ~11:5:1. The obd2 ecu's don't seem to have this problem.Dan 16s said:+40%? are U sure? at What RPM?
