2. Is a diesel tune safe for my engine? The safety of a diesel tune largely depends on the quality of the tune itself. Custom tunes, like those offered by Willys Workshop, are designed to keep the engine's specifications within their design limits. Generic, off-the-shelf tunes may pose risks if not well-engineered or if they push the engine beyond its safe operating parameters.
3. Will a diesel tune void my warranty? Yes, a diesel tune can void your vehicle's warranty. It is recommended to check your warranty terms and conditions before tuning, or consider a tune that is reversible for minimal risk.
4. How much does a diesel tune cost? Diesel tune pricing varies depending on the type of tune, the level of customization, and the shop offering the service. Custom tunes from specialist providers such as Willys Workshop will likely cost more than generic off-the-shelf options.

7. How do I choose the best diesel tune for my vehicle? The best diesel tune depends on your specific vehicle and driving needs. Research reputable brands, consider custom tuning options, and speak with a trusted mechanic.
