Contact HP Tuner through their support and submit a ticket. I got it figured out pretty quickly through them and then PBD got me my maps fairly quickly. It appears that $800 only gets you an RTD, 4 credits and 4 "canned" maps with no revisions. For a custom tune I think you have to upgrade upgrade your tuning plan.
EDIT: (7/27/21)
PBD has been very very good with supplying revisions as my modifications have been added. When you spend the $800 on the RTD, for the credits and for four tunes, you also get revisions. My only quip is that they are canned tunes (off the shelf) but they work really well.
