I hate to rain on your parade but that's pretty similar to what the few of us running 37's and 4.88s on TJs are getting.

I appreciate that compared to the TJ you are pushing a chamfered brick through the air... but at the heart of it, it's still a brick. There's probably a bit of a trade-off between the supposedly more efficient motor and the extra size & weight of the JK so I wouldn't expect it to be too much different from a TJ running 4-6" of lift and 35-37" tyres.

Actually I would have figured that given the rolling stock, your fuel consumption is pretty good.....

mate with all those changes your speedo is probably so far out, you have no idea what you are really getting. but really big tyres have a really big affect on fuel economy.....all bad.

i read in the latest overlander mag during offroad testing they were geting 29l/100km(i think thats what it was) on the stock jk unlimited

is the last 5000km since you've changed every thing ?? if it feels different after the change maybe ratios or something are right but if it was good after the changes and only been problem recently and you haven't got any obvious faults or been driving hard core offroad id deffinately take it to the dealer
