i have the stage five setup from fwdp, and was wondering what people are setting there fuel pressure at for the 40 over injectors. or, is this cal setup to run these injectors at the stock fuel pressure. the other issue i'm having is that i'm getting some detonation on full throttle runs(18lbs) at the beginning of each gear. i'm wondering if i set my fuel pressure to low, even though it lights the blue light on my dawes device. i also set the timing to 10deg insted of 12deg to try to help(it didn't). i didn't have this problem running 18lbs with my old setup(stock t2 with extra injectors).

if the cal was setup for the injectors you are running, then you should be using stock fuel pressure. talk to your cal vendor and explain the problems you are having, i assume that matching it to your setup is part of the deal.
