Hard to say. If you turn off traction control and the wheels spin, it's slower. If you leave it on and it kicks in, it's slower.
I suppose the best way is to accelerate at the limit of adhesion but how you accomplish that is the hard part...

I would say that, for a 545i, without TC will be faster in dry conditions and a semi-competent driver. It is for my E39 M5, and that's got 400bhp to play with - obviously turning TC off in the wet or icey conditions in that is a bit of a lottery...

My Ride: 2008 535i: June 6th start build, complete June 17th, at NY Port July 5th, at dealer July 10th, took delivery Friday July 13- Plantimum Bronze/Natural Brown Leather/Light Poplar, Sport Package, Sport Auto, Active Steering, Premium Package, CWP & PDC. Dinan Performance Software 384hp & 421 ft/lbs.
A limited amount of Wheel spin gets the engine into the powerband faster, thus faster acceleration. I would speculate that 4000 rpm is the optimum amount of wheel spin since BMW's Acceleration Assistant" launches at that RPM. Also if the car detects wheelspin with trac on, it will reduce power thus curbing acceleration.
So apply brake, DSC off for 3 seconds, floor accelerator, release brake.
Weeeeeeeeeeeeeeeeeeeeeeeeeee!
