BTW, I've never taken my Sprint Booster out for any service at the dealer (including a transmission replacement last month under warranty), I'm not sure why C removes his, unless it's for the reinstall and moment of JOY afterward!! 
But you're right. For the basic service updates, no need to remove it.

Can someone PLEASE answer this question:
(I have asked it 3x in other threads before
and have not gotten 1 response).
I realize this device does not add horsepower.
But does it make your car faster?
Let's use the 1/4 mile before and after SB
as an example.
thanks !!

I don't know why you guys like this thing so much. I tried it out and returned it, I felt like a 16 year old in a Honda Civic racing around. Just to jumpy for me, I would rather put it in manual mode and drive it that way.

My Ride: 2006 550i - Silver-Grey - Sprint Booster
Well, just came back from lunch - "Honey I'm not coming home!" Ha Ha Ha
Got a chance to get on the highway - MAN! Didn't even need to use Knockdown feature and I was zooming!!! Was able to move ahead people with no effort. People down in South Florida cruise 80 mph so a good inch of throttle zipped me past 100 mph and beyond. Don't get me wrong, I'm not a young boy and far from an old man, but I do love response from the throttle when I hit it. I didn't get the 550i to drive slow in the left lane. Before the SB I felt the lag, now I do not. I read before that it doesn't increase your 0-60 but the 550i did change gears, etc much better than before. I'm happy with mine and can't see myself returning it or selling on e-bay. Also, while I do enjoy speed, I never drive crazy in traffic. By the way, off the line felt much better.

why would you take out before going 2 dealership? so it reduces lag when u floor it?
