The boost gauge has been in the car for almost a year and havent had any issues.. im trying to find out if there is a boost leak or what but i am running 10psi with no boost controller.. i want to take it to shop for this issue but i dont know if they find a issue with boost gauge causeing boost to go up.. how is the stock line ran on the msp's before the boost gauge was installed i didnt install it soo i dont know how it was.. we used the hose and t clamped it near the throttle body.. anyoine with a digi camera stock no boost gauge take a pic for me i would appreciate it .. thx sorry for rambling on im just mad that it is doing this.. although it feels great!! to run 10psi

I've heard of a few people boosting high stock but 10 to 12 is nutz! I'll ask around and see if someone has some answers.

Your internal actuator is not opening. You either have a bad Vac line to it, or a bad actuator. I know a few people had thier actuators go bad, and ALOT have bad Vac lines.

If you feed from the intake manifold, then it can't be the boost gauge. You should check your vac line to the wastegate (from the T), it is really crappy and you may find a split if you feed from there. I strongly suspect that you have a leak somewhere.

I just had my second turbo replaced for this reason. First one was sticking open...no boost=suck

This one was sticking closed...lots of boost=fun until boom, then suck.

I think boostisgood is right on with the vac line or actuator.

The actuator is gone

check the vacuum line on your bypass valve. my car did that when that hose was popped off/coming off. if that's the case just put it back on or hell leave it off it ya want!
