From the Driver Seat Dynamometers put an end to many of the false and ridiculous horsepower claims being barked to the consumer from fly-by-night aftermarket companies. Whereas, there are still false claims, and plenty of fake performance accessories on the Internet, the legitimate companies have stepped up to the plate and are now delivering real technologies to trucks and SUVs. A perfect example of this is the DiabloSports Predator tuner. Dyno numbers vary from Mustang dyno, to Dynojet, to several others, but once a baseline number is registered and that same dyno is used, consistent dyno numbers can be obtained. Seventy-hp in the peak power band. The quicker, more responsive acceleration and full boost that is perfectly tuned to the air-fuel ratio is a work of art. Steve has a knowledge of tuning and engines that rivals any custom tuner. With the know-how and a chassis dyno, it's no wonder our truck runs like a racehorse now.
