Default Overboosting? - 09-12-2021, 01:57 PM

hello guys I'm quite new to this forum but been on the bmw scene for a few years .

I iwn a 2006 335i with uprated turbos fbo and meth running jb4.

I've had the car dynoed at 680bhp last year.
First had a major boost leak so had metal outlets fabricated
The car has been checked now with no boost leak issues .

I had it dynoed last week and I'm hitting 430. The guy says it seems as if I'm overboosting then its shutting down top end of the rev range ..

I've done a log which I will post .

Just trying to get down to the bottom of the lost power..
