Maximize the Efficiency & Torque of Your Fleet

Time is money. Fuel is money. Stop wasting both.

Whether you are hauling cross-country in a Cascadia, running local deliveries in an M2 106 Business Class, or navigating the city in a Sprinter, your Freightliner is a tool. But factory ECU settings often limit that tool, sacrificing pulling power and fuel efficiency for generic global compliance.

The Stage 3 "Heavy-Haul" Performance Module is engineered to optimize the workhorse under your hood. By refining the fuel injection timing and boost maps, this module helps your rig hold top gear longer on grades, reduces downshifting, and maximizes every drop of diesel.

✔ Improve Fuel Economy (MPG). ✔ Climb Hills in Higher Gears. ✔ Reduce Driver Fatigue.

Why Upgrade to Stage 3?

• Significant MPG Gains: In the logistics world, every mile counts. Our active fuel management optimization can yield +1 to +3 MPG improvements (depending on load and driving habits), paying for the chip in fuel savings alone.
• Massive Torque Increase: Safely unlock up to +75 ft·lbs of Torque. This is the "grunt" you need to maintain speed up the Rockies or Appalachians without losing momentum.
• Reduce Downshifting: By increasing low-end power, your transmission (Allison, Eaton, or DT12) stays in the efficient top gears longer, reducing wear and tear on the drivetrain.
• Eliminate Throttle Lag: Particularly for Sprinter and M2 owners, this removes the hesitation when pulling out into traffic with a heavy load.
• Universal Diesel Support: Compatible with Detroit Diesel (DD13/DD15/DD16), Cummins (ISB/ISL/X15), and Mercedes powertrains found in Freightliner chassis.
• No Downtime Install: Installs in minutes. No mechanic required, no long shop visits, and no cutting into the harness.

Smart Tuning for the Long Haul

Modern diesel engines are controlled by complex computers that manage DEF, DPF, and fuel rail pressure. The Stage 3 Tuner works with these systems, not against them.

The Efficiency Algorithm: This module monitors load percentage and turbo boost 500 times a second. When you are cruising, it leans out the fuel map for maximum economy. When you demand power for a hill, it safely increases rail pressure to provide instant torque.

For the Sprinter Van: It transforms the driving experience, making the van feel like a passenger car rather than a sluggish commercial vehicle.

For the Cascadia/M2: It acts as a "Torque Management" assistant, helping you maintain average speed without constantly mashing the pedal.

100% Safe, DOT Compliant & Reversible

We know your rig is your livelihood. You cannot afford downtime or voided warranties.

Emissions Safe: This device does not delete or bypass your DPF or DEF systems. It is fully compliant with emissions equipment. By optimizing the burn, many drivers actually report fewer Regen cycles.

Warranty Safe: The module does not flash the ECM. It leaves no "footprint" or digital record. If you need to go in for service or a DOT inspection, simply unplug the unit, and the truck returns to stock instantly.

Frequently Asked Questions

My truck has a round diagnostic port (9-Pin). Will this fit?
Most heavy-duty Freightliners (Cascadia/Columbia) use a round J1939 port, while Sprinters and some Medium Duty trucks use the standard rectangular OBDII. Please check your port before ordering. If you have the round port, you may need an OBDII-to-J1939 adapter cable.

Will this cause High Exhaust Gas Temperatures (EGTs)?
No. The Stage 3 chip is programmed to stay within safe thermal limits. It increases power by optimizing timing and efficiency, not just by dumping raw fuel (which causes high heat).

Does it work with Allison and Eaton Automated Transmissions?
Yes. The chip smooths out the torque curve, which helps automated manual transmissions (like the
