It has been discussed in some length here so if you want further perspective...dig around some recent threads.
Short answer is...no foul to running the stock map with Tors if you don't open up the airbox in particular. For optimal performance either Arrow map is better than the Tors map but only worth installing it if you make it to the dealer maybe for something else.
I run the stock map with Tors and the bike runs beautifully.
A further note, is remove the AI if you want a smoother throttle and no popping on decel with the Tors.
Cheers.
