    Basically, the higher the FD, the more revolutions the engine will have to do for that specific gear. Hence, increasing the FD will restrict the top speed that the car can produce. Does that make sense?

    With a stock box, (purely for example purposes) a car might be running at 50 MPH in 2nd gear @ 4000 RPM. If you increased the FD, it then may be doing 5000 RPM in the same gear at 50 MPH.

    The 1.4xsi box with a 7800 limiter will give approximately the same speeds in each gear as a VTS box at 7250rpm… so quite a good combination for a cammed VTS that’s being used on the roads

    Not too sure on the codes
