I'm a new hummer owner and have several questions. My hummer has 35x12.50x17R's on it right now if i add a leveling kit what size tires could I put on it? Also the gauges lights do not come on but they work fine does anyone know what might be the issue? Has anyone installed a gas chip and had good results? Also, mine has a roof rack that is 4" inch tall solid aluminum, would removing this rack relieve enough drag that would be noticeable?

 

I ran 37" tires in my H2 without leveling the truck. I lost about a mile per gallon when I added my roof rack.

 

No gauge lights may be your dimmer switch. Are your radio lights affected as well? Assuming the radio is factory.

 

I have installed the chip and after the first refill, my mileage went up 1.4mpg. This number may be affected by an emergency run I had to make in downtown Dallas at traffic time. I think the number will go up once I am back to normal driving.

Bite the bait ... what chip u got installed ?

 

I used the G-Force chip. It was around $75 with shipping. Easy to install.

 

Before installing the chip, my mileage on every fill up was either 9.9 or 10mpg. After installation, with a trip during rush hour and sitting on side streets for an hour, my mileage jumped to 11.4mpg. I am retired and only fill up once a week but it is always around 165 miles, so the driving has been the same every week.

 

Here we go with the chip dilema again! Lol! $70 for a chip that's going to add 60hp & 4-7 MPG savings! REALLY! I have NEVER EVER seen ONE of these Chips that have done ANYTHING! Think about it, $70 for 60HP-4-7MPG! Guys, REALLY! C'MON Man! Lol!

 

^well you get what you pay for. Think of Hypertech who sells their programmers for $300+ and on our rigs I think they give 21hp. Big difference in price and gains-I'll leave you to decide which one actually works.

 

No i don't have a stock radio but the dimmer switch does dim the ac lights. Also has anyone tried to rhino line/ line x the chrome grill and mirror back?
