Weird boost controll problem.

[Jeff822]

Ok, so ever since i sold my friend my old fmic and put back on the stock smic and piping my boost has been spiking crazy high, i since then got a new fmic and upper piping and when i got it there was a hole in the weld on the lower IC pipe, put some JB weld on that and still have to do another boost leak test. But here's my problem, boost is still shooting past 20 psi and i have no clue why, i backed my MBC off from 18 to 9 psi it held at 9 without a probelm at 1/2-3/4 throttle, so i bumped it up another turn to 11 psi, still holds at 11 psi at 1/2-3/4 throttle. Why is it holding at 11 psi but wouldnt hold at 18 psi? When it was set at 18 it would go to 5 psi like normal and then just shoot up like nothing. Now with it set at 11 psi it does the same goes to 5 like normal and shoots up but holds at 11/12 psi, i have yet to check for any pin holes or anything in the boost controller lines but none of them are kinked. Im hoping its not the WGA and just something simple and stupid, btw there is NO power what-so ever from the boost, i can hear the turbo spool and the see the boost gauge rise but i feel no power. Could there be a leak somewhere else? If anyone has any questions or anything or any info please share. Thanks, Jeff

Do a Boost Leak test. Then run the car with the WGA without a boost source and see if it boosts till infinity but be careful. This will rule out the WGA. Let us know what happened with the boost leak test.
