I wouldn't let it see 20psi again, very bad for your engine!

It should be overboosting on the dyno as well so it should have been picked up during tuning as well, I think?

It turned out to be the the values for the boost solenoid were not harsh enough to prevent the boost from running away.

Could it be the way the guage is set up? Link to comment https://www.fordxr6turbo.com/forum/topic/63604-boost-gauge-spiking-to-20-psi/#findComment-955088 Share on other sites More sharing options...
