Can the dealership overwrite my tune?

Yes. If the dealership performs a PCM software update, your custom tune may be overwritten and replaced with the updated factory calibration.

Not every dealership visit results in a PCM update, but it is possible anytime software updates, recalls, or drivability concerns are addressed.

If your vehicle receives a PCM update, simply contact our team. Depending on the circumstances, an updated stock file and tune revision may be required.
