Simple Installation, Powerful Results
Simple Installation, Powerful Results
Big Boss Tuners are hardware devices that connect directly to your truck’s ECU port, providing pre-loaded performance maps for popular diesel platforms (Cummins, Detroit, Paccar, Volvo, Caterpillar). With just a few minutes of installation, you can unlock:
- Up to 75 HP gain (depending on engine model)
- 100–150 lb-ft of added torque for improved towing and hill performance
- Enhanced throttle response and smoother power delivery
- 1–2 MPG improvement on highway runs under normal duty cycles
Big Boss Tuners plug directly into the J-1939/OBD-II port—no splicing or complex wiring. Our technicians handle the entire process: selecting the right pre-load file, installing the tuner, and validating gains via live data monitoring.
How Big Boss Tuning Works at Monson
How Big Boss Tuning Works at Monson
Vehicle Assessment & Model Selection
- Technician verifies engine make/model and ECM type (6-pin, 9-pin, or 16-pin).
- Confirm no active fault codes or active limp-mode conditions.
- Discuss customer goals: performance vs. economy focus, tow loads, and duty cycle.
Pre-Load Map Selection & Installation
- Select the appropriate Big Boss™ plug-and-play unit for the ECM.
- With the engine off, plug the tuner into the J-1939/OBD-II port under the dash or in the engine bay.
- Power the tuner by cycling the ignition to “On”—the device downloads stock parameters and writes the selected performance map (takes 3–5 minutes).
Live Data Validation & Road Test
- Start the engine and verify correct map installation via the tuner’s LED indicators or in-cab display.
- Technician connects a diagnostic scanner to monitor live boost, rail pressure, and timing adjustments.
- Conduct a controlled road test: monitor EGTs, turbo spooling, and fuel rail pressure to ensure all parameters remain within safe limits.
Customer Briefing & Documentation
- Provide a summary of gains: factory vs. tuned horsepower/torque figures (or estimated percentage gains).
- Explain map-switching procedure (if equipped) and demonstrate how to toggle between “Performance” and “Economy” modes.
- Hand over Big Boss™ user manual, map selection guide, and warranty paperwork.

Frequently Asked Questions
How do I switch between Performance and Economy maps?
Most Big Boss tuners include a simple toggle switch on the device or an in-cab display button. Our technicians will demonstrate the process and confirm map changes via live data.
Will this tuner void my OEM warranty?
No. Big Boss calibrations are CARB-verified and designed to preserve OEM emission controls. You can revert to the stock map at any time by unplugging the tuner.
What if I need a custom map for aftermarket parts?
We offer custom tuning packages starting at $295 extra. A technician will log into your engine’s live data under load, record parameters (boost, rail pressure), and adjust tables to maximize gains safely.
Can I install a Big Boss Tuner myself?
While the installation is bolt-on, we recommend having a certified Monson technician install and validate the tune. This ensures proper map selection, live-data verification, and avoids potential issues.
How long does the installation take?
The entire process—diagnostics, installation, road test, and customer briefing—takes approximately 60–75 minutes.
