So a little update...


Been dailying it but I think I broke something. The other day I was out "testing and comparing" and was slowly trying to turn the boost up as I was tired of it spooling to 8 psi then slowly spike to 14. So I turned the MBC a half turn, nothing. Full turn nothing. One more full turn then it spiked to 20-25 psi. As soon as it did that it has deveolped a 5-6 psi stutter. Feels just like a rev limiter and now it won't idle after it warms up. I can actually rev it all the way to redline as long as I don't go over 5 psi. Stutters with quick throttle blips sometimes too.

I've boost leak tested it three times now, all holding 20 psi before blowing my leak tester apart. Changed plugs to bpr6es from the 7's I was running when it happened. No change, and when I pulled them today are white. I have no loss of coolant, and I don't see any milk on the dipstick. Plug wires are 8.5mm Magnacores. I'm beginning to think fuel pressure issue? I really need suggestions as I'm out of ideas....
