You should try to datalog the duty cycle of your pump, injectors and rail pressure, along with A/F.

yes I agree, but the general concesus is that you don't want to go above 12to 1 unless you are running higher octane regardless of what the amount of timing it can hold. I know that my truck is a pushrod motor and not a mod motor and that it doesn't like the high a/f ratio with timing. I'm sure that there are exceptions, but most people no matter what the motor or type of car will run a a/f ratio between 11:1 and 12:1 on street octane.
