[X3rd Time Is a Charm]

I’m surprised that no one has mentioned a Throttle Response Unit.
I have the Pedal Commander on my 2018 X3, there are quite a few of them out there. Regardless of which unit you buy , the difference is night and day. Someone in the forum has the dahler unit which also has a valet and anti theft setting on it .
The car Accelerates completely different , depending on which setting you have it on It can actually be to to responsive.
If you want to get rid of your throttle lag , I recommend you look into these .
The difference Is crazy .
