oh ok so I shouldn't get the booster??? but I have got to wait until my warranty is over before I can do any re-mapping thats the problem. well, juan powerblow, I don't actually know what's the name of the colour but I know its grey.About the waiting period, I think we took the one in the showroom or they had the car ready so my dad and I only waited the normal 10 day period. What colour is your car man?
