after digging around my new car a bit i found it has a unichip box installed as well as what i assume to the the turbo/boost module component.

it looks to have the stock turbo (TD04) as well as a legal TBE (cat/res etc..)
and front mount. after changing the seized bov to a plumb back unit it drives really well, nice power delivery etc for my first wrx.

now my question is what kind of boost pressures would you expect to tune a car in this basic set up?
ideal and limit?

im yet to rig up a gauge and see where its at.

also with going back to the plumb back system is the factory ecu going to re learn the parameters or is it not part of the equation in these ecu's (+ the piggy back)
