I have no definitive figures but at around 120km/hr I used all 36 litres in the main and TT tank in just about 600km. It also didn't seem to make any difference to the way the bike ran.
I will venture out on a limb here, and say that it was installed incorrectly. Could be your dyno guy knows his dyno, but does know how to enable the AT in the PC-5 tool menu..... could be many things, and I am obviously speculating, but mine rocked a big difference with that same setup. Something was done incorrectly I think. My mileage went down 15-20 %, thus the system came off.
