So, mine is doing 55mph at 3000 revs in 4th. I didn't spec the axle so maybe they are just fitting the 4:1 now?

I'm at 58mph at the same (Sat Nav speed = speedo). Not that I know what this means...
Basically speaking, you have the Aero Racing diff ratio in your Mog. On a stock engine you will have the feeling of a tuned engine as you will accelerate through the gears quicker.
To understand more have a look here: http://www.performanceprobe.com/index2.php?redirect=http://www.performanceprobe.com/misc/index.php?do=calc&page=gearspeed
Play with the ratios in the diff, you now have your gearbox ratios and the you have your tyre sizes. The transfer the info to when your driving to see how the car feels in the rev ranges and gears.
