Hi lads, sorry to ask again, but really want to know what boost a MY95 WRX from Japan should run at with no mods.

Mine is running only 0.5bar on full boost and seems a little slow(ish)

Hope someone out there can advise me

Cheers

should be about 12.5 psi so def not right it sounds like its in limp home mode so you've got a problem with something mate.

Should be 12.7psi.
As mentioned above try an ECU reset by connection the green connectors to each other, and the balck connectors to eash other (under the steering column).

You will find the car will only run 0.5/0.6bar in this mode. Once you get the check engine light flashing again, stop and disconnect the connectors. You may find boost is back up to 12.7psi (0.9 bar). If not, your boost control solenoid may be stuck closed or faulty.

With ya head under the bonnet open the throttle slightly and you should hear the soldenoid start clicking. As the car goes back to idel and the throttle is closed, the clicking should stop (the solenoid is on the drivers side suspension strut top).

I hoe this helps....

You're probably running on baseboost at the moment. Do you hear any strange whistles or whines (like a demented windchime) when accelerating? If so, the diaphragm in your recirc dumpvalve may have failed. Pretty easy to check. Also check that your vacuum control hoses (such as those going to the boost control solenoid, the wastegate actuator etc) don't have any tears etc. Also make sure that they're connected and haven't blown off. If you have a boost gauge, check what vacuum you get on idle or deceleration. If it's less than before then it's a vacuum leak. Usually you should get -0.5 bar on idle, -0.7 on deceleration.
