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

with a low boost setup and stock injectors just use a missing link and fmu ditch the afc if you dont really feel comfortable the fmu setup has been proven to work and easy
you can mess with the afc but really need a larger injector and remove fuel to get that route to work well the afc is not the best way to add fuel its better at removing fuel.
