Add horsepower and torque to your ride with a DiabloSport Reaper Stage 1 performance kit. Each kit includes an DiabloSprt inTune i3 and Jammer cold air intake, keeping the guesswork out of determining the perfect programmer and intake combination.

The inTune i3 features a new and improved display that is easy to navigate in comparison to its predecessor. Most supported vehicles have the ability to remove the top speed limiter, adjust speedometer for different tire sizes, and adjust transmission shifting. There are even more adjustable parameters based on specific applications, everything from disabling the active fuel management, adjusting REV limiter, taking control of cooling fan, and much, much more.

The Jammer cold air intake includes a pre-oiled filter, and air box, and an oversized intake pipe. The air box helps to keep hot air from the engine, allowing the intake to pull in colder, denser air, and the thermal plastic intake tube further helps to reduce intake air temperatures.

DiabloSport dyno tests all of their application specific tunes to ensure maximum horsepower and torque. The i3 and Jammer intake are designed to work together, which will not only maximize performance gains, but will also avoid check engine lights. So, if you're ready to add some serious power to your truck, the Reaper performance package is waiting.
