I don't know why you are still arguing that TT diff is better. Your simulator shows that a 4.10 diff has an acceleration advantage. The blue line is the 4.10 diff in an acceleration vs time plot:
This overlay supports what people say about the 4.10 diff making the car feel lighter.
Also the more time you spend accelerating the better off you will be a 4.10 diff (i.e. road course) especially if you use those points right after 1st and 2nd shifts:)
