Hi mate, ive got a MY94 STi and that has a SA (pink) ecu and my boost is about 1.1bar and fuel cut is 1.25bar. Hope that helps....

looking at the SB map there doesn't appear to be a fuel cut. It's set at 22psi which is beyond the limit of the map sensor (which is about 17.5psi).

Fuelling is lean compared to a Z4 and 'achievable' boot target is about 13.6psi.

You would be better off with the Z4, certainly if you are thinking of manually or electronically raising the boost levels.
