Boost surge

[GotGrip?]

So, interesting development, boost is surging from 10psi-17psi at wot. As soon as it hits 17 it drops, then back up etc etc. Has anyone experienced this before? Going to log tomorrow once my laptop is charged, but wanted to get a jump on possible issues.

Have you double checked the zip tied hose at the bottom of the attached pic, to make sure it has come off?

Four out of five dentists recommend this.

I've got a nice little clamp on that hose, inspected all the vacuum lines last night, nothing appears to be ripped or torn. My next adventure will be going through all the couplers on the IC piping.

Brad was able to look at my log last yesterday and narrow down a few things, ended up being the boost solenoid. Thankfully i had a spare laying around from a couple years ago with low miles on it.
