There are other options, like EFI Live or HP Tuners.

I decided on EFI Live for a few reasons:
1. AutoVE Tuning Software is included with EFI Live, TunerCats OBD2 and Jet DST do not offer AutoVE Tuning Software.
2. The one license per PCM, for most all OBD2 computers.
3. I could download EFI Live and take it for a test drive (demo mode) before I purchased it: http://www.efilive.com/latest/cat/download-efilive
