Sorry about that [&:] You have alot of modifications though, which most people say have caused their H3's mileage to go down.  I am all stock, with the exception of a K&N air filter and the PCM upgrade.  I was going to get a cat-back and CAI kit, but I'm starting to have second thoughts.

Thanks HummerGuy I was feeling pretty good about that.  Getting about 15.5mpg.  Thats not to good, thanks for bringing it to my attention.


To be fair in your comparison, he has a manual, and you have an automatic. In general you will always see the manuals putting out more impressive gas mileage [:)]

Kelly, when are you going to have a pcmforless for the H2 because I would be interested

HUMMER DRIVER -> RE: PCM TUNING (10/23/2007 4:20:14 AM)

The catback (Magnaflow) didn't seem to hurt my mileage a bit. I was getting right at 20MPG highway until I put those big honkin Super Swampers on my ride.

I have a K&N intake, PCM update and dual exhaust. Like I said, mileage with stock wheels is great provided you obey the speed limit. Since going to the large tires I can tell you my mileage has suffered a great deal.. I don't plan to run the Swampers all the time. I will put my stockers on and click some hiway miles with them too.

On my old '06, the tires and the leveling were good for a 3 to 4 mpg hit ! ! !

The PCM tune on the totally stock '06 did seem to help, but I traded it in on the '07 before
I realized the full benefit of the tune.........

On the '07, with just the tires.....I'm @ 14 to 15 mpg on a good tank staying @ 65 mph mostly highway...

It just rolled over 2000 miles and I've only checked a few tanks. It's been in the shop more than it's been on the road,
so I really haven't had more than 2 consecutive tanks to compare...
