I just did the on demand throttle upgrade on my Level a couple of weeks ago. I really enjoy the difference in performance and safety. The level 1 and 2 assist modes are much less abrupt and the throttle on demand makes it much easier to get underway, especially when you get caught out at a traffic light and can’t shift to a lower gear. The install was easy to do and took about thirty minutes. I have about 1800 miles on my Level so far and no problems at all. Good Luck on your Level purchase!
