The programmers have real tuning options. I have two HEMI powered vehicles and both have the DiabloSport Predator programmer on them. They definitely improved the performance of the vehicles. The combination of intake, exhaust and a programmer on the RAM got me better performance and my mileage improved!
Like usual very true a quality intake,exhaust,programmer set up wont make ya broke like some hotrodding techniques but will give you a very nice noticable difference in performance
