Just quick update, the pedal box is working really well and I am enjoying the car much more, as far as wearing lead boots it's not that simple because it actually speeds up the response from pedal to clutch and you still feel that delay even when flooring the pedal.
I am now enjoying driving with a really light foot and have all the power I need with just a light touch of the throttle...not for everyone but it's made driving the gti much more pleasurable for me, it really does feel quicker too and just more thrilling to drive.....a driver's car.
