Turbo S2KI Stopped Boosting
The car was fine running at wastegate PSI but when I adjusted the Boost the PSI didnt change whatsoever. Now it doesnt seem to even be at wastegate pressure. I havent found any boost leaks, the turbo is fine, motor is great and AFRs are fine. I dont know what to look at now. Could there be leaks else where? How would I know? I could post some AEM logs if that would help anyone?

Sounds like he used the boost controller to adjust the pressure below the spring pressure and now there is no boost, but all else is the same.
Post the log files, or email them.

Q for OP, where was the boost level before adjustment? And why did you adjust it and in which direction?

This is impossible. A boost controller can NOT adjust boost below the wastegate spring pressure.
Exactly, this is why PeanutButter said it makes no sense.

You guys are confusing me even more, I never adjusted the boost controller below the wastegate pressure, I just had it turned all the way to the min and the min is just at wastegate, correct? Also is the the air coming out of the boostcontroller when i turn it up about 2 -3 turns, is that normal?

check the exhaust manifold to turbo manifold for an exhaust leak. The bolts may have backed out a touch, just enough to not spool the turbo. Be more specific if yo ucan.
