2011-2012 Silverado/Sierra HD(E78) Support released

[Bill@HPTuners]

Got the 2011 and 2012 definitions completed and added to the newest beta 2.23.628 or newer

We took a little longer than we wanted to for these but wanted to make sure the initial release as very complete so we don't need to revisit these any time soon.

If you do not currently have access to the newest beta software and would like access please email support at hptuners.com with your request AND your serial number and we will update your customer page as quickly as possible.
