Piko, what do you reckon. Will I be running too lean with 10psi @ max rev's? I don't have a AFR gauge installed but have clamped the MAF @ 4.7v.
The stock injectors don't provide enough fuel for much over stock boost. Didn't you have yours remaped?
Many people just run higher boost with stock fueling and the ECU takes care of knock by reducing ignition timing. It does a good job but you're loosing a lot of power that way.
