car struggling

[6III]

My car was running under boost (.4BAR) and the revs took forever to reach redline, and didn't rev as freely as it should. Today i took my car for a drive.. and it's not even hitting boost at all, and it really struggles to rev beyond 4000rpm. My car idles perfectly and it's not blowing any smoke at all.. I took apart the intercooler pipes and put them back to check for leaks.. but it's still the same, I've also checked the vaccum lines and things seem well too.. anyones input would be greatly appreciated, btw car is an evo3.

Thanks guys,
Phuc

Maybe turbine wheel is dead. That's my gut feel. Might pay to give Techsport or AFAS a call to check it out.

Shouldn't take them to long to take apart the turbo and have a look. :wink:
