Showcasing one of our 19–21 68RFE DEF Gauge SOTF tune packages 🔥

This setup gives the customer 0–180HP switch-on-the-fly power levels, controlled through the DEF gauge, with our Steering Wheel Control Fuel Management built in. Fueling can be adjusted from Level 1 standard boost fueling all the way to Level 5 low boost fueling max using the cruise control buttons.

Power Levels:
Level 1 — Stock / +35HP
Level 2 — +50HP
Level 3 — +100HP Tow Max
Level 4 — +125HP Hiss
Level 5 — +180HP Max Effort Hiss

This file is set up with rumble idle on levels 1–3, hiss idle on levels 4–5, low boost fueling, optimized boost/fueling control, improved throttle response, smoother power delivery, and transmission tuning to help the truck shift better and hold power more efficiently.

Tow it, daily it, or turn it up when you want to have some fun. This is how a 6.7 Cummins should’ve came from the factory.
