Angry What's the max boost showing on your factory gauge pack for WRX?

Just got my factory gauge pack installed on my WRX, and holy sh#@!! It's only showing .045mpa max which is like 7psi!

Is the gauge calibrated wrong? Or am I only getting half the boost I'm supposed to be getting? Does the ECU limit the boost until car's reached a certain milage? Or did the dealer screw the install? What reading are you guys getting? I do get up to -.09mpa of negative vacuum, -.07mpa at idle.

Another thing. Like others, the boost gauge only lights up only half as bright as the other two. Plus, the oil temp is on the right and volts in center. Isn't these two supposed be other way around?

As I understand, first gear is limited to around 7psi, so give it a shot at WOT in 3rd in the mid-RPM range (it tapers off near redline too).

Thats the whole reason a lot of people put boost controllers on the WRX's... not to give it more peak boost, but to even out the boost that it does get.

I see about 1.2 kg/cm2 or about 17psi peak pressure
This is during pretty hard acceleration but not WOT
Usually it's about 15psi peak. I hope my engine doesn't blow up.

Fubaru,
RUN THAT THING!!
You should be fine....are you still running the stock turbo?..all the computers that are coming out raise the boost to 15-17psi, so i wouldnt worry.

Rexy, actually if your factory gauge is setting at 0 with the engine off you have problems.

Deadbolt,

would you please elaborate a little bit? I believe all the meters should be showing "0" when the engine is off - no vacuum nor boost when engine is off, correct?

Why's that deadbolt? It has neither boost or vacuum with the engine off, so what else should it say besides 0?

Well, I have had the factory gauges since i got the car(12000 miles now, and when it was bone stock, boost would go just below 1 bar in 2nd, 3rd...etc, meaning it was showing correct boost, but when the car is off, it reads a little below zero, is this correct? OH man, I hope I am not running like 17 psi or something, cause with the ebc, I am running 1 bar, so hopefully its calibrated correctly. Deadbolt, i would also like to learn your wisdom.

I also first noticed that mine sits slightly below '0' when off. BUT if you lower your head so that the gauge is eye-level, the needle sits between the 0 mark.

BTW, turns out you gotta floor it to get max boost in stock form. Since I was breaking it in, I was babying it and only going 2/3 WOT. Stock turbo is not responsive at all. It only 'wakes up' at WOT. Boost controller fixed all that, of course. But I remember only getting .09mpa which is like only 13psi during post-breakin WOT runs.

Thanks Deadbolt...I know already because I installed my gauge pack and noticed what the booklet said. SOA tried to say that it was normal. I sent them the page from the manual and told them I was calling them on their BS.
