guys my car does nt feel the same i dont know what it its its losing power bad 2 weeks ago thisbad boy lit the streets now it feels as the turbo doesnt even work ,it still blows off but how can i know that the trbo is losing it baad

 

Thats could be alot of things, but start small. Tighten all of the hoseclamps along the intake tract, esp the one on the intake side of the turbo. If that doesn't help, check compression. Also, does it smoke at all? Or have starting problems?
