This is from Hypertech...

The computers on the 07- up vehicles are different from the earlier
versions. We definitely would support the earlier year models, if we get
enough requests for them.

Make sure to put in a product request on our website, so we can contact
you when they become available. The link to our product request page is
http://209.12.144.7/requests.php.

Thanks.
