Mines was done by Collins

took ecu out the car and sent it to them

they chipped it and sent it back following day (24hr service)

plugged it back in and went for a drive to settle car in etc etc before booting it

car was rollin roaded laters and i had a miltek exhaust system and pipercross induction kit and was the usual 12-15 bhp more than standard with it getting better and better each run

car drove nicer when chipped also
