Hey guys,
I have been wanting to replace my 3.07 gears with 3.55 gears. The Jeep dealer can't program the change and I purchased a HyperTech Speedometer Calibrator to see if it would program the change. I programmed in 3.55 gears with my Jeep still stock with 3.07 gears. I expected an error in speed or "limp mode" But it drove normal, no errors and no change to speedometer reading. I have been in contact with HyperTech.
That was the long of it, the short of it is they need a 2006 Jeep WK or XK to test programming on. They are located in Bartlett, TN. Any volunteers? This is our chance to get a programmer that finally lets us swap gears, if I was closer I'd do it. Any one willing and close enough to help?
