Re: Question for Hummer Pro's
Thanks for the tip Mud- yah, I am running a Superchips Cortex right now. It definetely helps from how it was running before right after adding the bigger tires, but my biggest thing is that most of the highways around here are 75, so I am needing to keep it between 75 or 80. Between 65 and 74ish, it runs great, but anything above that it is downshifting into 3rd. I guess I might as well start the quest for a supercharger, because I am not hearing good stuff from everyone about regearing. Mo $$$, Mo problems!

Re: Question for Hummer Pro's
One more question to add to this: If I do go with the regear, will my chip still help it to perform at least half way decent? I am reading everyone saying their ride is gutless after the regear, I wonder if my chip would help this...

Re: Question for Hummer Pro's
Gears will greatly improve performance with larger tires. Your programmer will still work and allow you to adjust for the tire size/gear ratio change to keep your speedo accurate.
