My present SUT has 37's on it with no gears and no supercharger. It's gutless.
Soooo, this weekend I installed a supercharger. Haven't driven it yet since I don't have the correct fuel block but I'm gonna try this way without gears this time.
I'll let ya know how it works.

Re: Question for Hummer Pro's
Thanks boys, looks like I am going to need to regear since I don't have $6 - $7 grand laying around.

Re: Question for Hummer Pro's
what type of chip are you running?
i have the hypertech tunner running the basic tune with 37"s and i have good pep and no problems on the freeway going 65-75.
the tunner asked if i had bigger tires and if i changed gears, it is supposed to adjust your shift points and add pep.
did your chip just adjust your engine power? did/does it adjust for bigger tires?

If you look hard enough, you can find some magnachargers used for $1500-3000. They are good to 100,000 as long as they were taken care of. Even if it has high mileage, sending it back to the manufactuere for a total rebuild would only be around $1200, still cheaper than brand new.

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.
