You can still get the tune from them if you buy a DP. They are not selling new ones but they are/were selling off all the already produced ones with codes to grandfather in the tune and support. You just need to find a vendor with their DP still, not sure if you can buy used and transfer but could check.
Alternatively, if you don't even care if it's APR as you seem to imply, then why not just go buy a tune from one of the vendor's still selling them? Uni and IE both still list them for sale on their pages.
