I agree with what you're saying Mike. I'm a technical kind of guy, and know my way around electronics. And my first impression of the sprintbooster was the same as yours. It sounds like complete hogwash. I know that it's not opening my throttle any faster. I know it's not doing anything but altering the signal sent from my pedal to the ECU.

The whole thing of the sprintbooster is that it FEELS different. A lot of people (including myself) like the way it feels.

(And by the way, nope, it wasn't me with the fuse. But thanks anyway!)
