Tried each and every one of those combos last night... wish I had time to complile all the numbers... maybe this evening...
The winner was S Mode... Competitive Mode... No paddle shifters
although others like to have everything off.
Reasons were with T/C off I got wheel spin once off the line and another time using tap shift from 1st to 2nd. When I had T/C off and got no wheel spin I ran the exact same time as with T/C on. (so I prefer to be safe and leave it on - comp mode)
Tap shift will take lots of practice becuse it's soooo slow to react. You have to anticipate the tap so it can really screw up a a good run (but save your motor...
) I gained nothing using it during a perfect run except for a chance to shift late and lose time.
One more note... it's easier to have everything off when coming to the line... That way you can do a burnout and just pull up to the line rather than stop to double tap back to comp mode. I still prefer Comp mode
