Does the job as advertised. Recently lifted my jeep and put 31" tires on. Prior to installing the calibrator, the speedometer was off 7 mph. When reading 55 on speedometer, GPS showed me going 62. After calibrator installed, speedometer is dead on with GPS speed tracking. Would definitely recommend and may upgrade to the max energy software.

Software did not seem to load properly...after contacting SCT, found that the instructions to update the firmware were wrong. Loaded fine after a long online update. JK runs fine on 87 octane program, a noticeable improvement in midrange power...some on the top end. Too early to tell if any fuel mileage improvement.
