Boost Gauge reading

I've had my 2002 WRX Wagon for about 7500 miles now. On the stock boost gauge, I never get more than .075 bar of boost, and that's fully loaded, 4 people, skis and stuff going up I-70 in 4th gear at WOT. As far as I know, I should be getting close to .095/1 bar of boost?...

Is this because of the altitude here in Colorado, or should I get my boost gauge checked? I remember reading somewhere that someone had to remove a restrictor plate from the line to the guage, but that doesn't seem right.

Subetek - if you've got any insight, please feel free to share!

Well, from what I understand, WRX's run about 11-12psi stock, which translates into roughly .75bar of boost. 1 bar is roughly 15 pounds of boost, which is above stock levels. But I don't have a WRX, so I could be misinformed.

I've read that they run 13.5 psi max boost. I believe .1 bar is about 14.5 psi.

Well, regardless, a boost controller would mend your woes...

True, but most digital boost controllers independently read and display boost at any point you set them in your vacuum line. This means it has 2 benefits in your situation.

a. Tests accuracy of your existing boost gauge

b. Allows full adustment of boost to whatever suits your pleasure. (GETS THE PARTY STARTED!!)'

Good luck, whatever you decide.

Spoke to the MRT Performance tech at Burt Subaru today and he said it's normal to run about 3lbs lower boost at this altitude...

Also when you are going out I70 the altitude is even higher, so it freaky that thats when you get you highest boost I get my lowest there. In Breck I get about 11 psi max, with max in Longmont being about 14. I have an autometer guage.
