2001 turbo 2500

My friend donavans daily driver truck tuned on 14 psi of boost right now driving good!

58x notch running good

finally have the 58x gen4 motor the LY6 running good now with a beta test box from EFI source, for whatever reason our setup was super sensitive with firing spark C and D not sure if others have had this problem, but changing the resistence in the CD output pullup resistors has helped so far, good enough to make some baseline pulls on franks dyno and we netted over 600hp on 14psi, and 640whp with a clean pull

sloppy firebird, almost runs 9s on first trip to the track
