my plastic bit is already butchered anyway! I have a larger cold air feed pipe in it going into the standard air box, so that it gets air rammed into it, rather than sucking it from behind the light. As for 11bhp, i remember reading it, but i cant see that from a chip lol! maybe 5, dont kno what it would be like wi the induction kit n exhaust set up to run on optimax. should be good
