I came to the thread because I was having issues with my builds with SSV Ti wire. I bought the 0.4mm one and was using their CSV. But to get somewhere decent i had to run it at 320F and was still getting a warm vape.. it was odd. And if I put anything in the 400F range it was way to hot and the DNA-200 will (randomly) kick out of TC. While the same build and Atty on a e-Vic-VTC will run very happy @ 420F with a good vape. After I found this thread I went and got the CSV's form Steam Engine, that was a whole different experience in my DNA, no problems at all nice Vape @ 430+ range and very smooth. After that I went in a hunt and downloaded the SSV CSV for the Ti 0.5mm wire, and that was golden. I'm starting to think I got the wrong wire from SSV (the pouch says 0.4mm) but have no way to measure a 0.1mm diff. Checked the CSV's and there is a big difference in the values between the 0.4 and 0.5 from SSV, so either I got the wrong wire or the 0.4 csv from them is way off. I sent SSV an email to check will keep you posted. By the way I was using a VaporShark DNA 200 mod, and agree that there is no need to preheat Ti, goes into temp almost instantly.
