WRX-STi

Hi All,

What pressure should an STi7 run at as standard?
Mine seems to regularly hit 1.3 bar, occasionally 1.35 - it seems high, but it may just be me?!

My MY00 hits about 1.2-1.25bar, does seem high if the car is a standard UK sti but your gauge maybe slightly out.

Hmmm,

I'm using a PSI3 - I would have hoped it would be accurate!?
Does the WRX run the same boost as the WRX STi?

The UK WRX run a TD04 turbo made by Mitsubishi where as your STI runs a VF IHI turbo a VF30 I think. So you cant really equate the boost pressures. If you havent done anything to it like exhaust changes, PPP etc and its running at 1.3-1.35 bar then I would say its too high. Worth speaking to your dealer.
