Didn't you say in a post you were going to lay off of it until you get a tune? Then a couple posts later your saying you were going into boost again, to see the same problem. Ummm....duh?

If you have done a VF upgrade on your WRX, make sure to install the restrictor pill if your not running a boost controller, as without it your car will also overboost. Or if you have your wastegate vacuum lines wrong your car will overboost. Nonetheless, get a tune and control yourself!
