ive been on the diablo forum, the folks that make the predator. i have it on my charger and works awesome. there saying there gonna have a tuner available for the jk soon .i had the superchips for the charger and swore it was the best untill the predator came out. im not saying the superchips isnt good but if there tuner is any thing like it was for the charger,300,magnum,and challenger . it should blow there superchips out of the water. also the predator was always beinging updated via the internet . which once superchips made there tuner for the charger they abandoned us and never did any improvments.
