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.
