I've been tinkering with it for a couple days and can't figure out what it is. After 5000ish rpms boost dies off to around 12 psi. in first and second it dies off around 4000 rpms. but up to that it will fluctuate from 14-16 in 4th and 5th. These aren't exact as they vary each time earlier it held 16 psi without fluctuating to 5500 rpms. I didn't push it past that as I don't like runing it that hard
It did this before when only 3 bolts were holding the turbo on when I first got it. The bolts are tight with stage 8 locking nuts so I know that's not the issue. I have an eBay bov but it was holding 18 psi to redline with it, but I switched back to the bpv setup to be sure and still have the same issue. Vaccume at idle was 19 now ranges from 14-18, if it idles steady it still ranges from 16-19. I can't find any vaccume leaks at all, the waste gate still has a firmness to it when opening it by hand. I'm at a loss, the only thing I have left to test is the boost controller but I doubt its that
