Speed wrong

So when I first installed my MPGuino it would read my speed perfectly however for the past few months if I go over 50MPH it starts to read slower with 65MPH=~48MPH and 75 dropping to ~40MPH.

its as though its missing some of the pulses from the speed sensor.

Anyone have a idea of how to fix it?
