Is a Diesel Tune Safe for My Engine?

When done correctly by experienced professionals, a diesel tune can be safe for your engine. The key is to choose a reputable tuner like Willys Workshop that offers custom tuning tailored to your vehicle. Ensure the tune is calibrated within the safe operating parameters of your engine.

Will a Diesel Tune Void My Vehicle's Warranty?

Depending on your warranty terms and the specific modifications made, a diesel tune may void your vehicle's warranty. It is important to check the terms of your warranty and consult with your dealer before making any engine modifications.

How Much Does a Diesel Tune Cost?

Off-the-shelf tunes are generally more affordable, while custom dyno tunes, like those offered by Willys Workshop, typically cost more due to the personalized service and expertise involved.

How Is a Diesel Tune Installed?

What Kind of Maintenance Does a Diesel Tune Require?

After a diesel tune, it's essential to perform regular maintenance according to your vehicle's manufacturer's recommendations.
