Frequently Asked Questions

• What is a diesel tune? A diesel tune is the process of modifying the engine control unit (ECU) to optimize engine performance. This includes altering parameters like fuel injection, turbo boost, and timing to enhance horsepower, torque, and fuel efficiency.
• What are the benefits of a diesel tune? Diesel tunes can lead to numerous advantages, including increased horsepower and torque, improved fuel economy (depending on driving habits), enhanced throttle response, and a more enjoyable driving experience.
• Is a diesel tune safe for my engine? When performed correctly by experienced technicians and with safe parameters, a diesel tune does not have to compromise engine reliability. Willys Workshop, for example, puts reliability as their top priority. However, improper tuning or excessive power increases can potentially cause engine damage.
• Can a diesel tune void my warranty? Yes, in some cases a diesel tune can void your vehicle's warranty. It is important to check your warranty terms and conditions carefully, and always disclose any modifications to your vehicle. Some tuners offer programs that are compatible with factory warranty coverage or are designed to minimise this risk.
• How much does a diesel tune cost?

Willys Workshop offers a range of options catering to different budgets.
• How do I choose the best diesel tune for my vehicle? The best diesel tune depends on your specific vehicle, driving needs, and budget. Consider factors like your engine type, desired performance gains, and whether you prefer a custom or pre-programmed solution. Research different tuners, read reviews, and consult with experienced professionals like the team at Willys Workshop to determine the best option.

Always follow the manufacturer's instructions and consider your technical skills before attempting to install a diesel tune yourself. Willys Workshop offers professional installation services.
• Will a diesel tune improve my fuel economy? While some tunes can improve fuel economy, it depends on several factors. Optimizing engine settings for efficiency can lead to better fuel consumption, but aggressive driving habits can offset those gains.
