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.
