in short answer... Abso-freaking-lutely

Some say that the EC tune gives quicker throttle response, and to a degree, I guess it does, but the SB is different. The SB is increasing the voltage to the electronic throttle, in essence, making it feel as if you pushed down the pedal father, but it also happens much more quickly, which is most important. Just the other day I turned mine off, and the car literally felt horrible, compared to what I am used to. I run on the middle (green) setting and it is perfect for me. I have had both the EC tune and SB for more than a year and highly recommend both, but IMHO the EC tune is more for power than quicker throttle response.
