What ignition system do you have?

Well if you got a guage you will see ya boost gauge bounce around if the belt is slipping, my first thought is a maf pegging, thats exactly what my car did with the stock maf on only 6psi too, eventhough you said it ran fine before. You could splice into the wires or if you have a scanner see what volts its going too.

everything is stock except 3g alt electric fan and deleted smog pump...and wats MAF pegging?

Your airflows sensor measures the incoming air through volts reading, but it only reads to a certain amount of voltage, after that it pegs out, i cant remember the exact voltage off the top of my head, but point is after that it no longer compensates for the air coming in because the sensor can only read so many volts happens a lot to supercharged cars.

hmm that seems like a good reason to check....any idea why it would happen now and not before?

What are the plugs gaped at? You could be experiencing spark blow out.

sorry i dont mean to rob the thread but when your mass air pegs do you need to up grade to a bigger sensor?

.54 should they be gapped diff?

PRO50SC

gap them at .030. Stock gap it too large. Are you running an MSD box? Stronger spark is a def upgrade for a blower car.

well the manual specifically said its ment to run on a complety stock car so i left them at the stock gap. they were .54 before and everything was fine. ill try .030 though and no i dont have and msd box
