Hey,
I dyno'd a totally stock R34 GTR - I mean 100% stock including exhaust and it produced 178kw's @ all 4 wheels.
But your boost seem to be far too low for stock. It should be around 1.0bar. You can even safely increase it to 1.2 without issues and then you should see some results around 230kw's even with the other mods you have.
Back in the days when my R34 was running low mods it was getting about 420-450km's from around 50l of fuel.
Now I don't get anywhere near that.
