MSX 150 Turbo Problem

[mhucul]

I have a MSX 150 with approx 19 hours on the engine. I am only getting 50% - 60% turbo boost (4 leds) and I max out at 6000 RPM. I replaced a hose (from compressor to wastegate solenoid – I think) that was rotting away. No real improvement in performance. Any suggestions on what I can check (I am not a mechanic)? I would take it into the shop, but I just spent $1900 on fixing my Virage Txi (44 hours) (fuel pump, flywheel, stator, and starter).

what else but the blow off valve , im not sure but its a common problem

[mhucul]

Is the blow off valve the same as the wastegate valve?

Sounds like a loose hose clamp on the intake hose. Which one I'm not sure but loose clamp will not give full boost.

make sure control arm on waste gate is not frozen open dumping boost
