99 GT Vortech V3 Si with CXRacing FMIC.
Ford Lightning 90mm MAF and 42lb injectors.
1st problem at the dyno: MAF counts jumping by 100 counts? IDK what this means. Tuner tuned it anyway. I runs like crap. Tuner said to change to a blow through MAF.
So I did. Had a bung welded on the intake pipe before the throttle body and installed a SCT BA5000 MAF.
2nd problem today at the dyno: MAF counts to low at idle, car stalls? Tuner says he can't do anything with it. Doesn't know what the problem is. Reinstalled the first tune.
Got home and checked all the MAF wiring, and MAF voltages. All checks out well.
I'm at the end of trying to figure it out and thinking about just returning everything to stock.
Any ides for a salution?
