unhacked MAS

How much boost can i run with a unhacked MAS. I tryed running 17psi but it felt like i was getting fuel cut. (the car would jerk hard at 4K) i have 510s and a 255, i checked for boost leaks to already.

With the safc and the 510's, you should be able to run 17 no problem w/out hitting fuel cut. With stock injectors, you can run about 15-16 psi.

I didn't see an adjustable fuel press reg in your profile. With that walbro 255 you are most likely overrunning your stock regulator causing it to be really rich....hence the sputtering.

What are your safc settings at? Do you have a logger? It would be best if you could post up a log so we can see what is happening instead of just speculating. Post up rpm, knock, maf, tps, and idc. This will help alot.
