The Granatelli Predator diesel tuner from Stylin' Trucks adds instant horsepower and torque to your 6.0L Powerstroke!  This powerful hand-held tuning computer plugs directly into your truck or SUV's diagnostic port, and in a matter of seconds downloads one of four custom tailored tuning programs for up to 85 horsepower and 195 ft/lbs of torque. In addition to power, this unit also fine tunes your automatic transmission shift points, extends the top speed limiter and returns back to stock with absolutely no trace of its use. Predator tuners are also available for most other gas and diesel vehicles.
