Tune your 6.6L powered truck in your driveway. As many owners are aware, the L5P ECM is locked from the factory. We're offering a tuning solution that includes the ECM unlock. The purchase of the Predator 2 includes the cost of sending the ECM in to be unlocked. Instructions on how to do this will be included with your programmer when you receive it. DiabloSport will unlock and overnight it back to you ready for installation in your vehicle. At that point, you can tune it like you would any other vehicle! This is the best solution available for adding some much needed performance and mileage to your L5P powered truck. Looking for more towing power? How does 75 HP and 150 lb/ft over stock sound? Seeking max performance? The Extreme Performance tune offers gains of 150 HP and 350 lb/ft over stock! These strong gains result in some incredible performance improvements. If you would like to knock 1.2 second off your trucks 0-60 times, you need the Predator 2! Some examples of new options for the L5P applications are the addition of both 'Throttle Boost' and a 'keep last drive mode' option. Throttle Boost allows users to make adjustments to the throttle pedal sensitivity right through the tuner. Everyone has a preference regarding throttle response, and now you can set it how you like it. The 'keep last drive mode' options is just like it sounds. Enable this, and your truck will remember the last drive mode you were in when you shut the truck off. Next time you start the truck, it will be in the same mode it was when you last shut it off.
