Hello st owners I am in serious need of help, I could not say for how long now but my boost will not go over 12 psi. I have to look at the turbine and see if there is any free play but I want to see if I can get some answers of what all could cause a loss of boost like that. Usually I am over 20+ psi. The only thing that’s done to the car are boomba bpv, whoosh dp, 2jr CAI. I swapped maps and went to default to see if it made a difference and nothing. I need to get a smoke machine or something to actually check for leaks I tried to feel for air and could not feel any in majority of the spots for a boost leak. Any help would be nice 
before I end up trying to get an oem turbo.
