It can be done through software re-programming in the ECU.
Resistance values are what the throttle uses to determine how much is being requested, and can be changed for %throttle to adjust according to what the end user wants; i.e. 100% throttle at 50% turn. See pics.
If you were in the market for an ECU flash you could likely specify to the tuner that you wanted this and they may be willing to do it.
I have no real world experience with flashes and ECU tuners, there may be someone willing to do just the throttle adjustments.
