i take it you got a sticker? and i suppose you have got it done or fixed by now but what i did with my cammed car. i took it to a car shop (shop were u got your mods) and they pit it. thats if they do that for customers, but it was great. i dropped it off with the main things done already like springs, wheels and exhaust changes and i believe they wound my idle up a bit so it wasnt AS lumpy and they checked the car over so it could pass straight away.
food for though for any one else needing to pit a car.
