Default 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!
