    the hose with the restrictor pill seemed to be the only one that was still good.

    Then either your car is pulling boost for some reason or your boost solenoid has taken a dump. There are 2 green test jumpers under the steering column, plug those in, turn the key to acc, then listen for the solenoid clicking.

    If not, there's your problem. If it does click, reset your ecu and go for a quick test drive, if you still have low boost. A data log will be VERY beneficial, can you get one?

    Oh and I'm getting an invalid attachment man.
