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+ ECM Upgrade Service now available — see below

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.

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-.

1

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.

2

Go up a level

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

3

Go down a level

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

4

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.

Hardware Required

What Do I Need
to Get Started?

HPTuners MPVI2, MPVI2+, or MPVI3 With at least 6 universal credits loaded

2022+ Model Year? HP Tuners ECM Upgrade Service now available — see below
2022–2024 Update

We have a huge update for 2022–2024 model year trucks. Before now, you were required to do an ECM swap with a pre-2022 ECM in order to receive tuning. Not anymore — HP Tuners just dropped their ECM Upgrade Service for the CM2450B. This allows customers to send their factory ECM to HP Tuners and utilize their own ECM for calibrations. This service is a significant price reduction compared to sourcing a pre-2022 ECM.

The Details

One-Time Send-In
Upgrade Service

This one-time service upgrades an original RAM CM2450B ECM and is required for tuning using HP Tuners’ software.

You must physically remove the original ECM from your vehicle and ship it to HP Tuners headquarters for servicing. Once upgraded, you’ll have full access to calibrate, log, and scan via the OBDII port.

Note: No IMMO relearn, crank relearn, or ‘Replace ECM’ function in VCM Scanner is required — as long as the ECM returns to the same vehicle it came from.

Everything You Need

Requirements

Universal Credits for licensing are not included in the cost of this service and must be purchased separately.

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.
