There have been a TON of Sprint Booster posts recently with a TON of bad information.
Here is an in-depth write-up to help clear some things up.
Article -> http://www.crosslake.net/~dbipes/sprintboo...rintBooster.pdf
A good/brief summary of the article from SchwarzeEwigkt on Bimmerfest:
"Read it for the in depth stuff, but the short of it is that the Sprint Booster is a little amplifier, nothing more. It increases the signal from the pedal box by about 30%, meaning that the ECU thinks you're pressing the pedal about 30% harder than you really are. You're effectively using a megaphone to make your will known to the committee.
This would definitely make the throttle feel more responsive since you're making a smaller amount of right hoof count for more, but know this:
For 300 bones, you get:
* A pedal that feels more responsive because the gain has been turned up,
* A pedal where the top third of the range of motion doesn't do anything since you've multiplied the signal by 30% and max it out by 2/3 throttle,
* And, the kicker, the same thing you would have gotten if you pressed the pedal a bit harder."

that's why i didn't buy one yet.. i wonder if this also increases gas milage, since you constantly pressing the pedal harder.
i want to try one.. but i wonder. is it possible to ride slowly (cruise in the neiborhood on 1000-1500 rpm) or it will make it hard to control?
