    Boost Leak tool?

    I'm still not convinced my 06 wrx is running at full boost, and I've brought this up on various occasions in different posts. I've taken it to the dealer and the repair tech test drove and didnt think it was any slower than an identical model on their lot. But after driving with my original salesman, and asking for an honest answer he replied that he thought maybe it was a little bit slower, throttle response not as noticable.

    So I really want to have it checked out, in the least expensive way possible. I'm not a gearhead and I wouldn't feel safe tinkering with different valvles and pulling everything apart to test something. I know theres been a post about a tool someone built to check for boost leak, but is their an easier way you guys would reccomend? Getting a dyno with diagnostics reading for example?

    What makes you think it isn't running at stock pressure (~11 psi)?

    And yes, a boost gauge would be helpful, butt dyno's are notoriously incorrect. Otherwise, you could buy a tactrix cable and pull some logs. That'll tell you right away if something is drastically wrong. I would also keep in mind that the car will run less boost in lower gears.
