How does a Diesel Tune work?

A diesel tune works by rewriting the code within the ECU to change how the engine operates. These alterations fine-tune engine characteristics like fuel injection rates, boost levels, and timing advance, thereby maximizing engine performance and efficiency, relative to the pre-programmed calibration.

What are the benefits of a Diesel Tune?

The benefits of a diesel tune include increased horsepower and torque, improved fuel economy, smoother engine operation, and a more responsive driving experience. A diesel tune can also unlock features like increased towing capacity.

Is a Diesel Tune safe for my engine?

A professionally executed diesel tune, particularly a custom tune performed by a reputable shop like Willys Workshop, balances performance gains with engine longevity. Overly aggressive tunes or poorly calibrated modifications can cause damage. Always prioritize a well-executed tune performed by someone experienced with your specific make and model.
