You arnt suppost to pull more then 20 right?

i pulled like -24% on a 50 trim -23% on a s256 at 24psi

if your running with out a return your fuel pressure is still at 58 psi, i know on my rc 750's i have my fp at 43 psi w/o the rising rate. and im pulling about 16 17 % on my safc at only 15 lbs. depending if you have drop in injectors your fp it soo high causing your actually cc# to be higher, meaning you need to pull more or get a return setup

your ECU thinks its 577cc, yours at 58 are 837cc thats a 145% differance you would need to pull about 45% fuel (actually less cause the mopar injectors are rated with diferant fluid and they will flow more

have fun

Time to get a real tuning solution IMHO. You "can" do what your doing, but you have already seen the limitation. you have a single point of control in a system that needs at least 3.
