There's a lag in throttle response when you first tip into the pedal that's very frustrating when trying to slip a clutch. It's even more infuriating when you're trying to rev-match your downshifts smoothly. It makes the engine slow to rev and the relationship between pedal travel and engine RPM is non-linear, making it difficult to get the revs you want. Fortunately, switching the car to "Sport" greatly improves the throttle pedal's response to inputs, but it still feels detached, like you're making throttle requests, not giving commands.

These engines don't have throttle valves, like old cars. There is a motor actuating the eccentric shafts in the Valvetronic mechanism. When driving the N13, I think the initial response is pretty quick. The lag you notice is due to the turbo taking time to build up pressure. The flywheel is also a bit too heavy, making the engine rev up (and particularly down) rather slowly. The pedal is not to blame.
