When I was N/A the car seemed to like ~13.4 on the dyno. I think anywhere from 13.0-13.5 on the stock motor is good. The 00-01 AP1 picks up a good amount of power up top over stock when its leaned out.

Was this using a VAFC or something that allows you to adjust fuel and timing independantly. I believe optimal AFR is much leaner when you are tuning with a VAFC.

Are you going to do anything to richen up the mixture before tuning with the VAFC? If not, you probably won't have enough margin for the VAFC to work with.
