The Tune Transfer Fee applies to people who have purchased a vehicle with an existing B-Spec Tune on it. In situations where people sell their cars with the B-Spec Tune, the new owner of the vehicle purchases the existing tune that was made specifically for the original customer. The seller of the car would be considered our original customer, while the buyer of the car is not technically a Buildjournal customer.

If any changes or modifications are requested on the existing tune by the new vehicle owner, a tune transfer fee is required. The transfer fee will transfer the original order number to the new vehicle owner, thus taking ownership of that order number moving forward and will be considered as a Buildjournal customer.

Our customers are able to take advantage of our free file updates in the future (if any), as well as our low-cost retune option if multiple versions of the tune is desired. These are perks exclusive to B-Spec Tune customers.
