From what I remember, he can run up to 30+ psi of boost which requires 
bigger injectors and preferably 101ron fuel!!! I believe the modern 
RB26DETT in top spec runs 2.2 bar but I could be wrong (that's the 
engine in the R34 GTR)

I do know the fuel is metered using what I seem to remember i scalled 
the hot wire method(?). The air flow prior to boost passes over an 
electrical filament and a computer pumps more or less current into it to 
keep it at a constant temperature. This relates extremely well to a 
measure of the air being drawn in, and the fuelling is matched 
accordingly. What the turbo does to that air is immaterial because one 
way or another, it's getting into the cylinders. I'm sure it's not that 
simple, and there's all the ignition issues to be dealt with also
