Not as loud as the flap open but ok..so keeping my flap back to stock..my 2 cents

I felt the same way, a bit of a lag, but when I changed the Airfilter to K&N filter in BMW origin box it was gone. The new filter is way thinner than the original and flows way better!
Car is now sounding a lot more both from the exhaust and the intake.
