if you dont have any boost leaks, then id say the turbo is no good.

I did boost leak test and cant find anymore vac leaks, I also took the boost gauge out cleaned it put on teflon tape and reinstalled.

Something is off here. Your vacuumn should be between 19-21. Either your gauge is insensitive or you have a leak. Have you tried misting throttle cleaner around hoses or couplers around the engine bay? If there is a leak the engine will suck in the throttle body cleaner and affect the idle.
