    Stock boost pressure

    Hi folks...n00b here...

    I just purchased a new '06 WRX last week, after a long list of Jeeps, trucks, and turbo diesel cars. My last "sporty" car was a 1992 Nissan Sentra SE-R, a far cry from the performance of the WRX. I've spent the last several years doing long distance motorcycle touring as well as some track time/Deal's Gap time on sport bikes, as I've always had the need for speed. I'm now getting back into performance cars after a long hiatus.

    After doing a little research I think a AP with a good exhaust will do the trick for me. I need to keep some level of reliability for my nearly 100 mile per day commute, and I'll need longevity - hopefully well over 100k miles without lots of repair. I'm no stranger to car work, having been a 20 + year experienced master tech (the last 8 years working for Mitsubishi before I quit wrenching), but I don't want to live under the car on the weekends. I only want to improve the performance because I think it could use a little more - which brings me to my question:

    What is the stock boost pressure supposed to be on a 2006 WRX 5 speed? My car runs ok, but I'm wondering if it is a little low on boost pressure...under full throttle & higher RPM I see .07 on the factory boost guage, which I believe translates into about 10 PSI of boost, right? Can anyone else with a stock '06 confirm whether or not that is normal boost pressure? Seems a little low to me. I did a search and found one post where someone said stock boost pressure should be around 13 PSI, but that was on a 2 liter engine.

    Help out a n00b, would ya?

    my friend just got an 06 and when we went to get a tune on it it came back as boosting at 14.5 psi, but with just a tune it is safe to put it up to 16.5 for everyday driving!
    hopes that hepled!

    Thanks for the replies. I'm still curious to know what other '06 WRX owners are seeing on the factory boost guage under full throttle. If everyone else sees .07 on that guage I won't worry about it, but if others are seeing steady readings closer to 1.0 I might have a problem that needs to be addressed.

    You should be seeing almost .09 mPa, on you stock gauge. If you dont hit that i would suggest trying a wastegate arm adjustment. That might help you out.

    Or take it back (you said it was an 06, right?) ... Either the boost gauge is defective, or you have a small problem.
