Still much too much lag for me. But my other car has the pedal connected to the throttle body with a physical cable - so that is what I'm used to. ECO PRO is a joke. Maaaaaaybe if driving on a long trip on a flat freeway with cruise control on. Otherwise why buy the BMW in the first place - just to impress the neighbors?
Yes the lag is unacceptable. Maybe acceptable for a Toyota Prius, but not a BMW.

You should bring it back to the dealer to check whether there are any software updates for your x1.

But at the meantime, you can try this throttle adaptation reset procedure:
1. Keep your foot off the brake and hit the start/stop button.
2. Hold the gas pedal down (all the way down) for 5 seconds.
3. Switch off the car while holding the pedal down.
4. Done

You should see a slight improvement.
