The Predator from Diablo Sport allowed us to choose from a handful of programmed performance tunes on the fly and only took about 10 minutes for the one-time download. For test purposes we concentrated on four different stacker tunes: Tow, Performance, Extreme, and Extreme RKL (Road Kill Larry. Don't ask). Another option allows you to reload your vehicle's original tune, which returns the truck to stock, and a trial option allows you to hook up the Predator to another vehicle for a demo time of about five hours.
