im looking at putting one on my a3 and was just wondering if i needed to upgrade anything? i have an aftermarket dumpvalve and also a air intake. i am also revo mapped
i understand it will run normally like my old one untill i get it remapped again to suit the variables of the k03s but should it be fine running one after the map or do i need to upgrade pullys etc?
i dont want it to go bang!!
