Choose Your Tuning

The GEN2 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.
