    HP Tuners Diesel Tuning Hardware & Software

    HP Tuners builds the diagnostic and tuning hardware that lets diesel owners see what their engine is actually doing and change it � MPVI interfaces paired with VCM Editor and VCM Scanner software for real-time data logging and custom tuning. CFM Diesel Performance stocks HP Tuners gear for Cummins, Powerstroke, and Duramax platforms, giving racers, towers, and daily drivers the same tools shops use to dial in a tune instead of guessing at it.

    Why Diesel Owners Trust HP Tuners

    The current lineup includes the MPVI4 interface, VCM Editor for custom tune building, VCM Scanner for advanced data logging, and the Diesel Switch for changing tunes on the fly from the steering wheel.
