So if you have a 04 and up TJ and have a lift with bigger tires, chances are your Speedo is off. Well you have to go to the dealership and pay about $89.99 to have them recalibrate the Speedo and even then they are not sure if it will work.
I have talked with Superchips and Hypertech and both say they are working on a programmer for the 04 and up TJ but no release date is set yet
I will post more as info comes available.
