After I upgraded my now quite old A3 with a 110 horsepower engine and a 6-speed gearbox, the speedometer readings seem to be a bit optimistic.
In the lower speed range, I have achieved over 10% improvement. Due to the lack of a proper outlet, I haven't measured it at BAB speed yet.
Unfortunately, I don't have the reference value of my old gearbox. Could it be that the signal sender provides a few more impulses than in the old 5-speed transmission?
