Fuel cut with a GM maf
 

I have 450s, 190 fuel pump, and aftermarket fpr. i have the maf set to 450s, any suggestions to trick it into not fuel cutting?

Bump the fuel pressure and retune for larger injectors?

Do you have it in draw through or blow through setup? If it's draw through you could have boost leaks causing fuel cut.

Bigger injectors or chip the ECU.

I didn't know there was a way you could change it from draw thru to blow thru. What switch is it on the board?

Draw-thru = maf infront of turbo (stock location)
Blow-thru = maf behind turbo

You shouldn't need to change anyting on the translator to swich from draw-thru to blow-thru. It's just the difference in placement of the air flow sensor in the intake tract.
