I love my beat but i always seem to have trouble in passing the guy who drives along the motorway at exactly 70. I just start to pass and the ecu limits me at about 7,500 revs.

I can go way above this in other gears so it strikes me that there must be a switch somewhere telling the ecu i'm in fifth. If I disable this I will get the little extra bit of go I need.

Does anyone have any ideas/info on this?
