EFI Live remains one of the most capable tuning platforms available for diesel trucks, with deep access to fueling, timing, boost, and transmission tables.

RDP Tuning uses EFI Live's AutoCal device to deliver full ECM and TCM calibration across Duramax, Cummins, and Power Stroke platforms — including older, pre-EZ Lynk trucks that need a different approach.

This is the tool behind the HP Tuners & EFI Live tuning package on the pricing page, built for classic Duramax, early Cummins, Power Stroke, and other supported platforms via bench or cable flash.
