heres the deal:

98 gs, t3 turbo, msd btm, msd a6, vortech fmu, msd intank fuel pump, intercooler, and that dang s-afc.

im having a real time tuning this thing. i dont live in an area where any body does this sort of thing and i need some help tuning my air and fuel with the afc. this may sound stupid but oh well...can i replace the afc with something else thats smart enough to know what to do instead of having to work from scratch? if not, how do i tune this crazy thing because the a/f ratio crap just aint workin and ive been told to use a multi meter but the o2 sensor has four wires and i dont have a dang clue. help me out somebody please!! thanks

 

check with the dudes in the forced induction forum. They are more informed on these matters.
