Strongest driveshaft?

So I got the new CF driveshaft in this week and headed to the track yesterday. I will say that the CF shaft is much "quieter" then the aluminum. Unfortunately, I now have a vibration to work out. On two of the passes I made I had every dash light regarding advance track and traction control come on with some other lights that I'm not even sure what they were(dash looked like a Christmas tree). By the time I'd drive down return road to pits they would all go out. Anyone seen this before?

Carbon fiber isn't invincible. My DSS CF shaft had the yoke separate from the carbon fiber. Sending it into them this week for them to look at. We'll see.
