Is It Safe

Yes, We keep all the stock DME safeties in place. However you are always taking a risk when you add power to any vehicle above OE spec.

What if I am not satisfied with JSRTuning?

No worries, I will take care of any issues until you are 100% satisfied.

How does the process work?

Shortly after payment and info, I will send a base map with instructions on Flashing and datalogging via email.

If I sell my car, does the new owner get tuning support?

Tunes are Non-Transferable. This means the new owner will need to purchase a tune if they want changes made to the map.

Unfinished tuning from lack of logging or contact will be the new owner's responsibility to purchase a tune in order to complete. Please contact me for pricing.

How Much Power Can My Stock/Upgraded N54 Turbo(s) Make With Your Tune?
