Why No Customizable Throttle Settings?
 

Why can't the throttle response be customized in the same way that steering effort, exhaust sound (with npp), and ride firmness (with mag ride) can be customized? Is there a specific reason why the track throttle setting wouldn't work well with the tour suspension setting? I can understand why you wouldn't want the more responsive track throttle setting when in Wet mode, but what about the other modes like Tour and Sport?

I'll bet it's partially due to emissions and FE, but more to do with: how the hell would they manage the Stabilitrak and PTM settings?

That's a good point on the stability control systems. If throttle response were customizable it might result in a lot of new stability control calibrations to account for the new combinations that would be available between throttle setting and suspension setting.

As far as PTM modes, I would think each of those modes should be set from the factory to be 100% optimized for track performance. So, the PTM settings wouldn't be customizable.
