Boost issues
08 HHR SS, 139,000 mi. When my car is off, my boost gauge reads 25 vac. When I turn it on it stays around that at idle. The needle goes up when I give it gas, but even at WOT it doesn't go higher than about 2 vac. Any ideas?

FYI - your post in the FAQ for SS has been moved to a more appropriate section - ie: here. Your duplicate post has been removed - and your two other posts (all the same) have been deleted. Please do not post the same question in multiple places!!!

One of the experienced SS owners will hopefully give a reply and give you a hand with this.

to the forums!! What the gauge reads when the engine is off is meaningless. But the fact that you're not building boost pressure is a problem. You need to get the OBD2 codes read and post just the alphanumeric part here, i.e. P1244 or whatever, not the description, which can be misleading. You probably have a problem with the wastegate or bypass valve.
