Hi Rickman,
Mine dropped a little after the first few tanks but the speed makes the biggest difference. The most economical is about 80kmh on the open road. When stock my JKU CRD 5sp auto could get into the nines on a long run at 80 but increased towards 11 @110km/h. The front AEV bar and winch added a little, maybe 0.3l per 100. The 3inch lift added ~ another 0.5. Most of my trips are between 11.5 and 12 on stock tyres.
Murchison do the computer remapping for your model.
