Do Premium users see a TTS and IF number for rides?
If so does that just require a HRM or is power needed?
Yes, if you're using a power meter. And it is based on the power data. And although not called TSS, I imagine it would be very similar, given that the TSS formula has been published for many years.

You don't get either without.
