Diesel Force™ Tuning
Max Power, Increased Torque, and Improved Fuel Economy
Monson Truck & Trailer Repair is proud to offer Diesel Force™ Tuning—a cutting-edge performance upgrade for heavy-duty diesel engines. Whether you’re hauling heavy loads, navigating steep grades, or aiming to reduce your fuel spend, our certified technicians use Diesel Force’s proprietary software to unlock horsepower, optimize torque curves, and fine-tune your engine for maximum efficiency and reliability.
Unleash Your Truck’s True Potential
Unleash Your Truck’s True Potential
Stock engines are calibrated for broad, nationwide use—which means they’re often conservative on power and fuel maps. Diesel Force™ Tuning re-maps your engine control unit (ECU) with manufacturer-approved files that:
- Increase horsepower up to 50–75 HP (depending on model)
- Boost torque by 100–150 lb-ft for improved hill-climbing and towing
- Optimize fuel delivery to gain 1–2 MPG under normal highway conditions
- Enhance throttle response for smoother, more immediate acceleration
With Diesel Force, you retain full compatibility with emission systems (DPF, SCR, EGR) and preserve OEM warranties. Monson’s experienced technicians handle the entire process—from diagnostics to final calibration checks—ensuring your truck runs stronger, cleaner, and more profitably.
How Diesel Force™ Tuning Works at Monson
How Diesel Force™ Tuning Works at Monson
Diagnostic Scan & Baseline Assessment
- We perform a full ECU scan using Diesel Force’s DSP5 interface (or J1939-capable scanner) to capture your stock parameters, current fault codes, and active emission settings.
- Technicians verify engine health: compression, turbo function, fuel system integrity, and sensor operations (MAP, MAF, EGT).
Selection of Diesel Force Map
- Based on your engine model (e.g., Cummins X15, Detroit DD15, Paccar MX-13) and desired performance level, we choose the appropriate Diesel Force file version—Basic, Pro+, or custom fleet map.
- Ensure the selected map retains proper DPF regeneration strategies and SCR dosing for SCR-equipped models.
ECU Reflash & Calibration
- With the engine warmed to operating temperature, we connect the Diesel Force interface to the ECM/ECU’s OBD-II/J-1939 port.
- Upload the performance map. The entire flash process takes 8–12 minutes for most ECMs.
- Tech monitors live data (boost, rail pressure, timing) to confirm values match Diesel Force specifications.
Post-Tune Validation
- Conduct a controlled road test under various load conditions (idle, highway cruise, hills).
- Check for any fault codes and confirm that DPF, SCR, and EGR functions operate as expected.
- Measure baseline vs. post-tune performance: horsepower/torque dyno sheet for Pro+ or customer request.
Customer Briefing & Documentation
- Provide you with a dyno summary (if applicable) or data-log screenshots showing gains.
- Provide “before and after” fuel-economy projections, engine temperature logs, and EGT comparisons.
- Issue a Diesel Force™ certificate of tuning with warranty details, calibration version, and date.
Key Benefits of Diesel Force™ Tuning
Key Benefits of Diesel Force™ Tuning
Immediate Power & Torque Gains
Unlock up to 10% more horsepower and 15% more torque without replacing major hardware—improve hill-climbing and load-pull performance.
Enhanced Fuel Economy
On long-haul drives, you can save up to 1–2 MPG; over a year, that can translate to thousands in fuel cost savings.
OEM-Approved & Emissions-Safe
Diesel Force files are CARB-verified and keep your truck within allowable EPA and state emissions limits—no risk of voided DPF or SCR warranties.
Optimized for Aftermarket Modifications
If you’ve installed a cold-air intake, high-flow exhaust, or upgraded intercooler, Diesel Force customizes the calibration to extract every bit of performance.
Smooth, Reliable Operation
Carefully engineered torque curves reduce engine lugging, eliminate throttle hesitation, and improve drivability under all load conditions.
Proprietary Safety Parameters
Fuel-rail pressure and turbo boost are capped to protect injectors, turbos, and pistons—Engine Safety Mode engages if any parameter exceeds safe limits.

Frequently Asked Questions
Will Diesel Force™ Tuning void my OEM warranty?
No—Diesel Force calibrations are CARB-verified and designed to maintain full compliance with OEM emission systems. OEM hardware warranties remain intact. Monson’s workmanship warranty covers us for re-flashing errors or tuning mishaps.
How much horsepower and torque can I expect?
Gains vary by engine model, but typical results for mid-range diesels are +50–75 HP and +100–150 lb-ft of torque. High-performance packages can push beyond those numbers with supportive hardware.
Do I need any hardware upgrades before tuning?
For a basic tune, no additional hardware is required. However, if you install a cold-air intake or upgrade your exhaust, we can recalibrate to take full advantage of that aftermarket equipment—recommended for Pro+ customers.
How long does the tuning process take?
The ECU reflash itself takes 8–12 minutes, but we allocate 60–90 minutes total for pre-tune diagnostics, flashing, road testing, and validation.
Will the DPF/SCR/EGR functions still regenerate properly?
Absolutely. Diesel Force maps preserve all OEM regen parameters. You’ll still see periodic active and passive regens exactly as before—only now with less backpressure and improved efficiency.
