hey guys, im running absolutley discustingly rich.

i have done so much testing and nothing seems to work!!! im getting sick of trying to fix this POS

- so rich it doesnt let me boost over 5 psi- so rich it bogs out and i cant just punch the throttle- so rich i have a constant stream of black smoke

My setup is as follows

- s13 redtop SR- Stock everything- Starion FMIC- Ford Probe BOV (re-circ'd)- Stock injectors/FPR- NGK BRK6ES11 plugs gapped to .28- Timing is DEAD on- TPS reads .44 at closed and 4.5 at WOT- CTS reads 3.5V at OT- KA24E (SOHC) MAF, reading correctly and wired right (just match the color of the wires right? black/white to black/white, black to black, white to white?)- Coilpacks were recently replaced and are bolted down nice and tight.- pulling around 10 InHg of vacuum, at idle and between 10 and 20 at cruise

Like i said it wont boost past 5 psi without breaking up, i hooked up the stock boost control solenoid as per the FSM hoping that it was the wastegate and i could simply fool it to open later. but that doesnt seem to have fixed it.-

I have NO boost leaks, my BOV is recirculated, i have no leaks after the MAFS
