Seriously. I think this might actually work. Basically you just shorten the range for the signal to get to 100%. And I think the SB does the exact same thing - maybe the signal isn't altered linear and more agressive but this might come close.

The only thing I would do different: I would remove the bottle cap (or whatever else you use to shorten the pedal range) after recalibrating the throttle sensor/tcu. Then you still have to press the pedal all the way down to get to the kickdown switch but you have the full throttle signal about 1" earlier.

Or am I missing something here?
