Hi everyone. I'm new on this forum and was a 2006 H2 owner previously.
we sold the hummer when gas prices went thru the roof at $4.00 way back.
I've always missed it and now I have the opportunity to get a 2007 or a 2008 H2 SUT with 96,000 mileage for $23,000.
But before I buy it, I was wondering if theres any tuners out there to get this gas mileage up.
10mpg is not going to cut it. Any information greatly appreciated.

 

Ebay fuel magnets, copper fit tail pipe cover, and a wire in MAF performance resistor. That ought to do it.

 

How much better mileage will I see with this modification?
how much do these modifications cost?
I'm definitely interested to hear more on this.

 

zero -0- zero its up there with tin foil hats and free energy

 

Gas mileage is already up, now you can buy 2 gallons for the previous price of 1. Recently it was under a buck a gallon. Simple math, your price @$4.00 per gallon @ 10mpg=40 miles at a buck per gallon, or 20 miles @2bucks per gallon.
Who buys a Hummer for fuel economy????

 

Buy it, enjoy it and fill the tank as needed. Nothing you can do will make much of a difference.

 

I had mine custom tuned and deleted the cats and the best mpg I get is 13.9 to 14.1 highway.

H2 is not the vehicle you want if you even have to think about fuel economy.

Agree.... About the only way to conserve gas in an H2 is dont drive it.
