yes these little box of tricks are awesome my cooper s is so responsive now theres hardly any dip off in power between gear changes ,the only thing i can say is drive one of our cars next time we meet or if your really daring just buy one , fit it , and watch the grin get bigger and the heart race faster it also seems to smooths out the flat spot which R53 has on pull away fitment takes less than 5 minutes so go on dont eat for a month and enjoy
