Mini Cooper S R53 throttle response

[torquehappy]

Hi all,

I've had my R53 for a few months now and love it. What I don't love though is the drive by wire throttle response, the revs are just so slow to pick up.
I'm thinking of getting a Sprintbooster as they do seem to solve the pick-up problem and users seem happy.
Has anyone on here fitted one to a 53 and can give feedback? I'm aware that there aren't any benefits apart from tricking the ECU into thinking the pedal has been planted more. And no, planting the pedal more isn't the answer to the revs delay!
