question on those with a sb with the mode selector: if you select a mode (say sport or racing) and you turn off the car, when you start the car again would it be on the same mode selected or it would be "off" again and you need to reselect again?

it doesn't really apply to the manuals as the only tranny lag is from your foot to the clutch. I had to drop my C off for a bad gas gauge last week and they gave me a c300 4matic as a loaner. i really don't want to offend anyone here but man, that thing is like driving a 95 ford astrovan. it has ok acceleration but its got to be between 3500 and 4200 rpms in the power band and even then its so gradual and smooth. NO tq. YES, it was in sport mode. i had the loaner for 2 days and never once even bothered with comfort mode. bottom line, the SB is ideal for the lag on our drive by wire systems but i'm telling you guys, the difference between the manuals and auto's are night and day...doesn't even feel like the same car.

Yes.
You have to remember that *all* a sprint booster does is lies to the ECU that you have pushed the throttle down further than you actually have. It shortens the pedal length (electronically) so that you are already 'flooring it' before the pedal reaches the floor. This means that the last part of your gas pedal travel is now dead, useless. If you floor a car with a SB and a stock car next to it, they will accelerate identically. If you push the stock car to half throttle, and the one with the SB to 1/4 throttle, they will both accelerate similarly (I have no idea what the actual mapping is so I am making up this 1/4 number but you get the idea). The point is that it really does nothing. Just putting it out there for those reading the thread. No need to flame about it. Running away from the thread now. Enjoy your SB!

I assume then that there will be a similar response improvement in both economy and sport modes also, that would be good to have sport mode respond even quicker than what it does from factory.
The economy mode in diesel MB's is very sluggish from standstill, but livens up alot when in sport mode, I assume setting the sport mode does a similar 'factory' electronic change to what the SB does.
