HPTuners × 6.7 Cummins

Shift on the Fly.

Six power levels, one finger. The 2019–2024 6.7 Cummins finally gets the tuning platform it deserves — dialed in, EPA compliant, and accessible from your factory steering wheel. No switches. No drilling. No compromises.

2019–2024 Only 2500 / 3500 Pickup 49-State Legal 2022+ requires ECM replacement — see options above

What's Included

6 Shift on the Fly Levels

SOTF0 through SOTF5 — all accessible from your factory cruise control buttons. No third-party switches, no drilling. Just power on demand.

Pedal Response

Drastically improved throttle response and overall drivability. The truck wakes up the moment your foot hits the pedal — loaded or empty.

Speed Limiter Removed

102mph wasn't enough. The factory speed limiter is gone — because sometimes the open road calls and your truck shouldn't be the bottleneck.

Exhaust Brake Memory

Tired of turning your exhaust brake back on every time you start the truck? It now stays exactly where you left it. Set it once and forget it.

Transmission Tuning

68RFE only: line pressure raised from 160psi to 170psi, L/R clutch fix for sprag rolling, UD air test disabled. Builder-specific calibrations available up to 250psi.

Hundreds of Hours of Dev

Dyno-proven across multiple trucks, thousands of road miles, and a 6-week SEMA Garage independent test. This is a finished product — not a beta.

Dyno Results

Real Numbers on Real Trucks

Tested on our in-house Dynojet 224XLC2. Chrysler rates the Standard Output at 370HP/850TQ and the High Output at 400HP/1000TQ.

Using Your Tune

How to Change
Power Levels

No app. No Bluetooth. No switches. Just the cruise control buttons already on your steering wheel — Cancel, RES+, and SET-.

Check your current level

Press Cancel once without pressing anything else — the dash will ding and the lightning bolt flashes to show your current SOTF level.

Go up a level

Press Cancel, then press RES+ the number of times equal to the level you want. 5 presses = SOTF5.

Go down a level

Press Cancel, then press SET- to step down. Each press decrements one level from wherever you currently are.

Confirm the change

The dash dings and the lightning bolt flashes the number of times matching your new level. 3 flashes = SOTF3. Simple as that.

49-State Legal & EPA Compliant

Built the Right Way

This calibration underwent hundreds of hours of dyno development, hundreds of internal revisions, and thousands of road miles across multiple trucks before release. To close out development, we drove a 2019 2500 Standard Output from Florida to Southern California to the SEMA Garage for their SC-E program — a rigorous 6-week independent product test. The result: a verified, EPA compliant product with test data submitted to CARB toward a full 50-state Executive Order.

FAQ

Common Questions

Will this improve fuel economy?

We wouldn't expect any changes in fuel economy. All known methods to squeeze extra MPG out of these trucks also raise NOX emissions — which is against compliance requirements. If economy is your goal: skip the lift kit, run conservative tires, and keep a light right foot.

Will this increase regen events or hurt my emissions system?

Under normal driving, no change in regen frequency. Your DPF catches soot whether tuned or not — if you're hammering it from every stoplight on SOTF5, you'll soot-load it faster. Drive responsibly and you'll notice no difference in DPF cycles.

Will this change my DEF consumption?

No. The entire DPF/EGR/DEF subsystem remains fully functional exactly as it left the factory. DEF consumption is unchanged.

Can I remove my emissions components with this tune?

Definitely not. This is an emissions-compliant product — all components must remain intact. There are no codewords, no workarounds, and no exceptions. The answer is no, full stop.

I have a Cab & Chassis truck — is SOTF supported?

Not currently. HPTuners does not support SOTF for Cab & Chassis trucks. Single tune files can be provided for C&C applications — reach out and let us know your specific power level requirements.
