I have a 2010 550i (after coming from a 535i). I have to admit that the 550i takes a while to accelerate at lower speeds. If I don't estimate my acceleration needs a couple seconds in advance, I don't seem to get the good power.
I am not sure whether Sprintbooster will solve the issues, but the hestitation sometimes kills me.
Why pay for the bigger engine and take the fuel economy hit to lag behind a 535i?
I agree that at 60+ MPH, the car has great pickup.

So does M mode. Its much more consistent even starting out in M2. If you want the power, start in M1. No lag there, you just have to be light with the throttle or DSC cuts in.

My Ride: 06 550i Titanium Gray/Auburn interior. Sprintbooster, RPI Scoop W/BMC Filter, RPI exhaust, 20" Miro 111
How would the 550I do with the RPI bits, exhaust, scoops, and sprintbooster.

It is all about the driver when you're talking about streetlight races. I've beaten some seriously overpowered cars and been beaten by some severely underpowered ones way back when I used to get into this kind of things.
At the end of the day, the power-to-weight ratio in both - 550 and 535 is about the same, so acceleration should be near-identical in identical modes/stages of tune.

Of course, a 535 with a good tune should smoke a stock 550 as those tunes give the car over 400 bhp.
