Out of the blue my Profec B has no control over my boost. Non-seq and it shoots to 17 psi now no matter what- profec B on/off, hi/low etc.

Anyone have any experience with this? Can they just up and go bad? I've checked the lines and everything appears to be attached as normal.

Help please. Thanks!

 

Eek! Are you sure the wastegate line didn't pop off or develop a leak?

that is not a profec b problem.


if it was off, it should be doing 7 lbs or whatever your turbos minimum is.
