My car is a 1992 eagle talon tsi awd, mods are wideband, 2g maf, evo 560cc inj, safc 1, walbro fuel pump (not sure which one),boost is set at 9lbs, every thing else is stock except ported head..
So far from what I read, the 2g maf leans the car out 20%, and if I had 660cc injectors it would richen it up 30%, so if i have 560cc injectors it should even the ratio out, right? The problem im having is about 4500 rpms and above (at wot) im having a cut/hesitations, the wideband at wot is anywhere from 11.0 to 11.4...so im confused on why it is cutting. I dont have a logger or egt gauge so i can't tell what my timing or any of that is doing.. need some help.
