I wouldn't let it see 20psi again, very bad for your engine! Link to comment Share on other sites More sharing options...

It should be overboosting on the dyno as well so it should have been picked up during tuning as well, I think? Link to comment Share on other sites More sharing options...

It turned out to be the the values for the boost solenoid were not harsh enough to prevent the boost from running away. Link to comment Share on other sites More sharing options...

Could it be the way the guage is set up? Link to comment Share on other sites More sharing options...
