I see what your saying, but I needed an ECU that sees boost and not airflow, hence G60 setup CE1, and not the standard CE2. The plan is to then get the ECU chipped and remapped to suit the turbo setup, although I'm guessing that (on factory spec) as the boost increases the ECU would see it and increase the fuel anyways as its good for upto 1bar, around 15psi, and I'd only be running at the most upto 12psi, the waste gate should take care of the rest.
