its run in already, a mate run it in on his bed. i didnt keep doing it i done it once when i pulled off to get out as the rounabout was packed and was ther for ages (thats when i saw the boost go up id been below 3k for 4miles before that on the A13)then once straight after to be sure that it was creeping up and it wasnt a "one off".
i understand about the running it in and i bealry hit 4k when i pulled off. so i wasnt booting it i just pulled of enough for the boost to come (im not a boy racer and dont want to blow my new engine up).
