Clean Your Boost Controller!

[SlowWhite]

I'm having a problem with my Boost where No matter what I can't get it to sit at a given PSI.

the spring is a 17psi spring so I turned my boost controller almost all the way out. (to the point where the knob section is about to fall off)

And still today I did 2 pulls to 8Krpms and was seeing it climb straight to red line.

At least it was going up slower then normal but still climbing to 20psi. (the other day it was climbing to 25psi)


I don't think it's creep because it never stops at any given psi and then climbs. It just keeps on going. It's a big turbo so there is plenty of Lag.

I blew out both my tial gaskets but - yesterday I swapped them out and used the Hight Temp Copper RTV that's rated to 700degrees that I was told to use instead.

Anyways I can't quite tell what's going on. MY MBC is 5 years old. and I think the spring is probably just stuck Since I ran 20psi basically the entire time. Even the screw part had rust on it.


One thing I did notice is that when trying to clamp down my Waste GAte to my manifold the outer edges had a gap as if the manifold wasn't perfectly flat?

Or as if my dump tube is resting against my 02 sensor and prying it up. Cause it was a PIA to mount the waiste gate with the Dump tube attached first.
