Resolved. I was able to follow these specific instructions explicitly and it connected with full access.
***What ended up working***
1. Installed Techstream
2. Installed X-Horse MVCI driver software.
3. Swapped the Main.exe hack file.
4. Turned on TS and entered Location, User, etc...but did not activated it.
5. I went to my car, opened TS, then plugged in ODB and USB. Windows automatically prompted for the cable driver to install.
6. Clicked on "connect to vehicle", TS popped up and asked for the key. I then entered the key and it activated.
7. Pressed continue and the USB connected to ECU. It recognized my car model, year, vin number, etc.
8. When TS entered the SYSTEM SELECTION menu, everything was there (ie. Health Check, Customization, etc.).

Help Can't get Techstream to function
Weird thing is I had used this before with full access on my 100 series. Not sure what changed but I did a full re-install with the directions above and it worked.
