Exact mpg avg is 17828miles/1564gal = 11.4mpg

70% city driving 20% highway, 10% off-roading.

With 18,355 miles I am getting 13.6+ every tank and my average has risen to 13.2 and still climbing slowly with a supercharger installed at 6,000 miles.

Love the power and the fuel economy.

On the 2005 H2 you have to figure it out yourself. No more instant mpg.

The kit comes with simple instructions and everything you need to get your engine tuned. And, in as little as 20 minutes, the PROFLASH programmer will unlock the unexploited power in your engine. No other hand held programmer on the market offers the reliability and versatility of the PROFLASH programmer.

2. I doubt it, but KenP can answer that question.
