I've finally started to mess around with the predator tuner that came with my car. Before I messed with the tune, my traction control was turned off completely. I've opted to turn it back on because lately I've been driving in the rain a lot.

I guess my question is simple and possibly silly? Is there a benefit to having the traction control turned off rather than being able to turn it off/on at will like I just retuned it to be?
