PedalBox Tuning?

It sits between the pedal and the ecu to distort the signal being sent from the pedal. Never used one so can't comment on how well they work. I'm not in any rush to try one though.

In all seriousness - if you Google "Pedal box tuning"......the owners of many different cars across many different forums give great reviews !
