Hi my map sensor on my escort cosworth is knackered and needs replacing, I heard there's a place near Brands Hatch that do good ones, but basically what is the best map sensor to have that's more than 2.5 bar? Thanks.

 

3 bar? 4 bar? 5 bar? Depends on how much boost you want.
But you do need to get the car mapped (again), to cope with the new map sensor.

 

It's mapped to 3 bar I believe

 

It won't be mapped for that.

The Escos is an exception and the only one with 2.5 (for overboost)

You will need the same one, as the scales (thus mapping) are different.

It would be wise for you to find out exactly what map sensor you currently have, as you're providing very conflicting information.
