Recently bought a new to me 98 5 speed with 5x14 injectors, studs/o rings, 4K GSK, 60lb valve springs, afc live, 19* timing, 62mm high tech turbo and I’m sure I’m missing a few things.
Anyway I noticed I really only have heavy fueling at 20+ psi of boost with extremely low pre boost fuel in 2nd gear the truck struggles to build power until the turbo starts to boost. Little to no smoke at preboost. Checked afc position but it was all the way forward. I haven’t adjusted the preboost screw yet, anything else I should check?
