Fuel Cut #3

[Andrew7dg]

Stock exhaust?

When I replaced my exhaust, major boost creep happened and it would go to like 19 psi. BOOM, fuel cut... But you Probably have a gauge to look at that.

I would get fuel cut all the time in my car just because of the exhaust

Do you have something with MMcd To see what the computer is seeing? Have you looked at your FTs? I had to adjust mine to the GM maf-t because it was off. Thats why there are adjustment knobs in the box. Every GM maf reads slightly different. GM ECU corrects this already but we are working off of this box.

These tuning knobs shouldn't be used for tuning bigger injectors. IMO they suck because they only tune LOW, MED and HIGH and there needs to be more points to tune with then just three. An SAFC ontop of the GM maf-t for tuning would be Ideal. If you were to do that though, the 2G MAS plus and SAFC reads much much better then the GM MAF-t (I have had bad experiences with the MAF-T). I believe the SAFC also takes into account Trottle position.
