Unlock More Power, Cut Downtime & Eliminate Emissions Problems for Good

If you own or operate a Freightliner truck running a Detroit or Cummins engine, you’ve likely dealt with the constant headaches caused by modern emissions systems—DEF, DPF, and EGR. These systems were designed to reduce emissions, but in real-world trucking they often lead to expensive repairs, derates, downtime, and reduced reliability.

At TM AG Tuning, we specialize in professional DEF, DPF, and EGR delete tuning for Freightliner trucks. With over 10 years of experience, nearly 300 dealers, and thousands of successful deletes across North America, we provide the most reliable and proven solution in the industry.

We make the process easy: we supply a prepaid UPS shipping label so you can send in your ECU and ACM safely and quickly. Once received, our tuning team completes the delete and optional horsepower upgrade—then ships everything back ready to plug and play.

What Are the DEF, DPF & EGR Systems in Your Freightliner Truck?

1. DEF (Diesel Exhaust Fluid) System

The DEF system is part of the SCR (Selective Catalytic Reduction) process. DEF is sprayed into the exhaust to reduce NOx emissions.

Common DEF system issues include:

• DEF pump failures

• NOx sensor failures

• DEF crystallization

• Incorrect DEF quality readings

• Costly derates or the dreaded 5 MPH limp mode

2. DPF (Diesel Particulate Filter)

The DPF traps soot and burns it off during a regeneration cycle.

Common DPF problems:

• Constant regens (every few hours or even minutes)

• “DPF Full” warnings

• Soot overload

• Cracked DPF filters

• Expensive replacements costing $3,000–$6,000+

3. EGR (Exhaust Gas Recirculation) System

The EGR routes exhaust gases back into the intake to reduce NOx.

Common EGR issues:

• EGR cooler failure (coolant loss or white smoke)

• EGR valve sticking

• Carbon buildup in the intake

• Reduced engine life due to soot contamination

Benefits of Removing DEF, DPF & EGR on Freightliner Trucks

When TM AG Tuning professionally deletes these restrictive emissions components, your Freightliner truck becomes more efficient, reliable, and powerful.

✔ Improved Fuel Economy

Removing emissions restrictions reduces backpressure, often improving fuel economy by 5–15%, depending on the truck.

✔ More Power & Torque

We can include a safe horsepower increase at no extra charge if desired. This helps with towing, hauling, and maintaining speed on grades.

✔ No More Derates or Limp Mode

Once deleted, you no longer need to worry about:

• 5 MPH derates

• Forced regens

• DEF dosing issues

• Soot buildup warnings

✔ Increased Engine Life

Without EGR soot contaminating the intake and oil system, internal engine wear is significantly reduced.

✔ Lower Operating Costs

You permanently eliminate:

• DEF fluid purchases

• DPF filter cleaning

• Sensor replacements

• Unnecessary dealership diagnostics

✔ Plug-and-Play Reliability

Your Freightliner arrives back tuned, tested, and ready to run without any coding or setup on your end.
