Choose your Tuning

Derringer is a plug-and-play solution for the L5P Duramax. It connects to your truck via the OBDII port and gives you 6 different power levels to choose from and has ActiveSafety to protect your engine. The Derringer doesn't write anything on your ECU, it only adapts the parameters to safely make more power. This means the tuner is untraceable by the dealer and will not void your warranty.

Add an Intake

Adding an intake isn't about power, it's about reducing the restriction, increasing efficiency, while maintaining strict filtration standards. These kits are offered with a Oil Cleanable Filter and Dry Disposable.

The Oiled Filter is recommended for those that mainly use their trucks for City or Highway driving and would rather clean their filter instead of replacing it.

The Dry Disposable is a better option if your truck frequently sees dusty environments or you'd rather toss out your filter instead of cleaning it.
