i wouldnt trust the boost gauge.

Checked against another boost gauge (cheap splitfire one)..... Same result!

time to check for a boost leak I think....

V5/V6 sti peak at 16psi then taper to 14psi at higher revs

correct... i wouldnt think it would hold boost all the way through to 7,000rpm

will taper off to 14psi as mentioned

Cool, it seems to ramp and hold @ 14 psi from around 3500 rpm.

Don't think anything is wrong mate. My apexi el2 boost gauge also reads at 1 bar/14psi. As said above I wouldn't trust a boost gauge for accuracy either.

800mmHg would be classed as maximum supercharging pressure..

800 mm of mercury = 15.4694198 pounds per square inch

your cat maybe stuffed/partially blocked from disintegration, this can affect boost levels

Blocked cat would reduce power too..... She has plenty of get up and go.

I thought they ran 16.5-17 for some reason....meh, don't know why!!?!!

Yeah I always thought the 99/00 WRX ran 1 bar (~14.5 psi) and that the STi was around 16 psi...
