H&S Performance Diesel Tuners
The XRT Pro is the solution that can meet almost anyone’s budget and needs. This product comes with all of the tuning capability of the Black Maxx / Mini Maxx but without the digital gauges and automatic defuel capability. GM and Ford vehicles will still be shift-on-the-fly capable (instantly change power levels), while Dodge vehicles will take approximately 10 minutes to change power levels.

The XRT Pro is capable of tuning the 6.7 Cummins engine and transmission SEPARATELY. This becomes handy for those running products other than H&S for their horsepower, but would like to tune the transmission with the H&S Overdrive software. For this application you will select "Transmissions ONLY" on your XRT Pro the first time it is installed on a vehicle.

The XRT Pro can tune the Engine AND Transmission on your 2007-2011 6.7L Cummins. You simply need to select your engine from the XRT Pro vehicle selection menu, and you will be given an option to unlock transmission tuning when you install the engine software onto your truck.

XRT Features:
  • Comes preloaded with DPF Present and DPF Removed capable tuning
  • Allows removal of the DPF system and ALL related sensors (nothing needs to go into the race exhaust)
  • Precisely tune engine with HP increases of 0-250HP
