I think the factory limited maximum available power until rpm and throttle position values were exceeded. To expand on that, I think that, for example, at 2000rpm and 100% throttle (really, pedal position) the maximum power the engine could provide was never delivered. What the engine can really do is not so artificially limited with the VAP tune. Since the engine can provide quite a bit, the pedal can be more sensitive, but it one can adapt.
