My 370z is far better on the TCS than the 350z (276) was. The '50 was so jerky and very voilent when the TC kicks in. The '70 is much more gentle, sometimes you can only tell its working as the light is flickering. Saying that it doesnt come on very often so hard to tell, but its certainly a lot smoother, doesnt just cut all the power, keeps power going even when its working, just reduces it enough to stop the slip.
