Re: disconect battery and then rubbish fuel economy
Let the ECU relearn, usually takes a week i've found. My trip computer said that i was using alot of fuel (after the reset), but by the next tank it was back to normal.
Apart from the cam have you got any other mods ? the bigger the cam usually the more fuel you'll use, but not that much with only the one mod.
