Hi all. My father bought me a DTUK pedal box for my car last week and such a difference it has made. I already have the tuning box, (map 2 +3) which I find very impressive in both power delivery and smoothness, but the pedal box has helped with response no end. It was very easy to fit, and I currently have it on sport 1, which I find to be just right. I had tried it on sport +, and whilst the response is even sharper, I find it perhaps a little too much for daily driving.
My last car was an astra j vxr, and whilst I find the golf better in all regards, the vxr button on the astra did sharpen it up more than sport more on the golf. With the addition of the pedal box this is no longer the case, and I find the car more pleasant to drive normally and more fun to drive quickly. I definitely recommend one.
