I've just been looking at a N plate STI type RA (Or at least that's what the VIN suggests) with a boost leak + other issues.

With my laptop software things & underbonet observations, the leaky pipes have been replaced and it's a lot better. (Long story involving a HKS boost gauge )

The boost is 11.5 PSI with no spikes - an improvement over the sluggish 10 PSI it had. This seems a bit low for an STI? I was expecting 12.5...

The turbo is a TD05 too. I thought STIs had some VFxx. Or is this only the later ones?

All help gratefully received!
