for shifts

mph and rpm both have to be met in order to make a shift true....if rpm isnt being met then compare shift mph vs actual mph.. raise mph till it matches the rpm



with 8 psi you can easily get away with 1degree of timing deduct per psi...so figure what your motor NA would normally see and start removing timing from there. on 8psi you can run 20* timing easily with a AFR of 12.0
