i have a 94 mx6 with a jspec engine, i bought the chip thats supposed to have the right vris points etc, well after installing it, its running so friggin rich it bogs out, ive heard all i need is an FPR to lean it out, but i was wondering what would work better, an Safc, or an fpr? and whats the main difference, never done in electric mods before, see the fuel etc is all new to me

if you shed any light on this, thanks in advance!

John
