What do you recommend for optimal fuel pressure (with and without vacuum) on 1988 vette with all the "cheap mods", high voltage ignition, ported plenum, no pre-cats, magnaflow cat-back and ram air?
Just got off the dyno and got 278hp from engine translated 262hp from rear wheels. Best torque was 530Nm.
My ignition timing was 7 degrees advance and I was thinking of trying new pull with 10 degrees and a little more optimised fuel pressure.
