			It's an emissions/ range (MPG) thing.
 As stated the tip S has adaptive learning and if you drive aggressively, you'll notice a significant change in shift mapping.
 
 That said, it will not allow over-revs, it'll shift just shy of redline.
 
 It does have a sort of primitive launch control though. At a stop, depress the brake and get on the throttle. You'll see it shift down to 1st gear.
 
 Cheers!
