Am I correct in thinking that the pedal box just plays with the throttle mapping and theoretically shouldn't be any faster down a drag strip with or without one?The feeling of torque you want will be best provided by a Pedal Box IMO. I went APR Stage 2+ and was underwhelmed by the low down power and torque and so went to MRC thinking that may be the solution. Not much difference, but slightly better I thought. Then got a pedal box and boom its amazing. Does away with the factory laggy pedal and makes the car feel it has instant torque with no jerkyness. See my review and comments in the current Pedal Box thread.
Not sure what you are trying to say here - are you advocating a larger turbo for the RS3? If so no, it is far from the answer for low end torque.I am really impressed with the torque curve that the RS6 produces, but then again it it a different story. Would a bigger turbo not lag TQ in the low range rpm ?
