Howdie all!
What I have here today is a 2002 Lingenfelter 725hp 427 twinturbo.
The tune is not a Lingenfelter and it is a little rich (10.5) with inconsistent boost control (7psi through 3500 then climbing to 11-12 at 5500).
When I made my first run on the dyno the intake tube with the MAS popped off. When I got to looking inside it was saturated with oil. The more tubes
I took off the more oil I found. Long story short- turbo seals are shot and pumping oil into induction.
Turbos are coming out and going for rebuild. Tubes and charge coolers are out for cleaning.
Now, is there actualy a safe way to clean the GM MAS meter or should I toss it for a new one?
I live in the world of MB & BMW where an oiled MAS goes into circular file.
