Hi my car is remaped already and I want to install smaller pulley is necessary to remap again ? If yes any one can recommend good tuner in London/near London?

Yes , if you fit a smaller pulley the car will benefit from another remap.

Eurocharged seem to have the best map for the 55k engine and you have them in Watford.
