What are the benefits of a diesel tune?

Benefits include increased horsepower and torque, improved fuel economy, smoother engine operation, and customized driving experiences.

How much does a diesel tune cost?

The cost varies widely based on the type of tune (pre-programmed vs. custom), the complexity of the vehicle, and the tuner's experience. It typically ranges from a few hundred to over a thousand dollars for the best options. Willys Workshop offers competitive pricing and packages that can be discussed during a consultation.

How is a diesel tune performed?

Tuning can be done by flashing a new program onto the ECU or through the use of a piggyback tune. This often involves connecting a device or the tuner to your vehicle's OBD-II port.
