I just went from 24lbs to 30lb injectors and noticed I had to lower the fuel pressure from 42 for the #24's to 35psi for the #30's other wise anything about 2500-3000 it fell flat on its face the car has a gt-40 longblock, b cam 1.72 rockers, cobra upper-lower intake a 1 in phenomic spacer, 70mm t/b 73mm maf, with fuel pressure@ 35lbs its snappier but still feels like its holding back a bit..any suggestions??? thanks :damnit:
