Question for you turbo experts...

[JShadzi at aol.com]

Rob, keeping efficiency and IC size in mind, I'd say the 12-15psi range max.  Lower boost levels will result in proportionally better power increase and lower intake air temps, maybe in the winter the 15psi will be more appropriate, during the warmer summer closer to 12psi.  Your 1.8 bar chip should be perfect overall, I'd start with that.
