Not having had a sprint booster fitted, I can’t agree or disagree with the findings. However, it does appear to “deaden” the last 1/3 of pedal travel, which could be disconcerting (ie the pedal peaks at 2/3 of its usualtravel). My guess is that you could physically stop the pedal where it peaks to give you the “it’s on the floor” feel.

I think I’d rather look to other software mods to up the BHP if I wanted some extra kick (remove the limitations built into the ECU for example). According to this document, Sprint Booster does not improve acceleration, rather it gives the illusion by reducing the point at which the throttle peaks.

I am guessing that it feels that the car is faster because your foot is not as far down on the floor for the speed you are doing. I noticed this a lot when I started driving my Crossfire this year. 70mph on my previous car was in a totally different place on the gas pedal to where it is on the Crossfire. As such, the Crossfire feels quicker in part because muscle memory is telling me “this is 50mph” when I’m doing 70.

My (cheaper, and somewhat tongue in cheek) solution: heavy boots and a good hard stomp on the gas!
