Clogged vanes?ralleyquattro said:Another issue arose. I was getting only 7-10psi of boost, needless to say it didn't feel as brisk as it should (this is on the stock computer).
Pulled codes and got one for G61 (2142).
Replaced the knock sensor this evening, what a PITA (had to move the P/S pump out of the way).
Anyhoo, took it for a nice drive and still the same. However no codes (4444).
Also have a new N75 valve in there, thought it could have been a problem.
Throttle opens all the way (thought maybe the Full throttle is not triggered), that's not the issue.
No boost leaks that I can see.
Any other reasons it won't build full boost?
Starts at 7psi then raises to 10psi as rpm go up.
I have not checked if the ECU calls for full boost, but the wiring between N75 and ECu is fine.
