For guys who are getting over 400+ km, I presume you are babying the car most of the time? I would be lucky to break into the 300km, guess that’s the down side when you drive your car once a fortnight.
Mind you, I do remember getting over 400+KM when the R34 was stock as a rock. The pod and exhaust threw the fuel figures out the window. Would love to see what happens once the turbo, cooler, injectors and pump gets done ))
