Dear Customer, During the past year, Diesel Spec Inc. (“DSI”) has been made aware of ongoing investigations led by the United States of America’s (the “US”) Environmental Protection Agency (“EPA”) into the sale and service of certain tuning products in the United States.

As a result, DSI has decided to make some major changes in its operations in the US market.

We have decided to stop all sales and services of any kind whatsoever in the US, effective December 22nd, 2022.

We understand that this is significant news and that it will invariably impact your business.

We are truly sorry for any inconvenience this may cause, but we consider that, in the circumstances, we are left with no alternative, and we need to make the best decision for DSI and its staff. Accordingly, we will not be able to honor any warranty on tunings, parts or any other services provided by DSI in the US past December 22nd, 2022.

Based on the foregoing, all DSI tools will need to be returned to us on or before January 31, 2022.

We undertake to cover all shipping charges related to same.

We will contact you to email you a return label to facilitate this process.

Any security deposit paid, will be fully refunded for all tools returned by the date indicated above that are in good condition and that have not been damaged or tampered with.

Again, we sincerely apologize for any inconvenience this may cause.

Should you wish to discuss, please do not hesitate to contact us.
