2022 Ram 2500 6.7 Cummins 68RFE in for the full setup.

This truck came in for an ECM swap and was tuned through EZ-Lynk with cruise control switch-on-the-fly. No extra switches, no clutter, just clean factory-style control through the steering wheel.

Power levels are set up like this:

Level 1 — Lope Idle / Stock HP
Level 2 — Rumble Tow / +50 HP
Level 3 — Stock Idle Light Tow / +100 HP
Level 4 — Rumble Sport / +150 HP
Level 5 — Hiss Idle Max Effort / +200 HP+

We also paired the engine tuning with custom 68RFE transmission tuning. Increased line pressure, firmer shifts, raised shift points, better converter control, and full lockup strategy to help the transmission hold power better.

Tow/haul mode gets 2nd gear lockup, while normal mode gets 3rd gear full lockup. The truck also has increased torque converter gain, higher pressure per gear, and 90 PSI constant at idle.

Unlocked shifts are also built into the file, meaning the converter unlocks during the shift and relocks once the shift is complete for a cleaner, more controlled shift.

A good tune is not just about making power. It’s about making the truck drive better, tow better, shift better, and live longer.
