2013 - 2018 Ram Cummins 2500 3500 4500 5500 | EFI Live

**If you purchased an EFI LIVE License ONLY for $125, you are confirming that you already have a flash device (AutoCal or FlashScan). If you do not know what either of those are you need to select the AutoCal Device + EFI Live License option to flash your truck.

Get more from your 2013-2018 RAM 6.7L Cummins with custom EFI Live tuning designed to improve horsepower, torque, drivability, and overall performance. 

Available for RAM 2500 through 5500 pickups and cab chassis applications, tuning can be configured with a single power level or CSP4 switchable tuning with selectable levels from 30HP through 180HP. Compatible 68RFE-equipped trucks can also be paired with transmission tuning to improve converter lockup, shift strategy, line pressure, and torque management. 

Tuning is deployed through an EFI Live AutoCal or FlashScan device, with licensing and hardware options available for customers who do not already have a compatible flash device.

Switchable Tuning

CSP4 Switchable Tuning includes four power levels:

• 30HP – Heavy Tow

Power levels can be changed using the EFI Live AutoCal Device or a physical Cummins CSP4/CSP5 OBD-II Pass-Through Switch.
