I haven't owned TTS, but I've owned earlier SE Race Tuner which was TTS rebranded. I can't comment on the newer VTune functions of TTS now that they are selling independently.
That said, the computer based interface is obviously different between TTS and PV, but what you are manipulating is the same. TTS has a few more tables you can tweak, but the PV is catching up. The Delphi ECM has a lot of 'stuff' that no aftermarket tuners can touch and in the end all you're doing is updating the exposed tables on the Delphi.
Canned maps, Dynojet has quite a few online and they can provide additional maps if you contact them directly. I'm not sure I understand what you mean by base maps to compare. Stock, Stage1, etc?
You can download the WinPV software and maps from Dynojet and mess with them even if you don't own the Tuner, good opportunity to prepare and learn. I did this before I got my PV.
