Engine temps affecting rpm?

[Benny Dub]

Alright guys, took the chim to Thorpe park today with a couple of mates (had a well good time lol) but noticed something quite perculiar.

When the engine is cold, in 5th at 2000rpm I'm doing about 70ish. But when the engine is fully warm, in 5th at 2000rpm i'm doing 90-95?

Is this true or are my gauges faulty? Bit worried as to the reliability of my dials now...

cheers
Ben

You must have the version with temperature controlled gearbox ratios.

It maybe that you have a bad earth and it's nothing to do with the temp.
