Take the air box off and put a nice big cone on it,dont forget to add a heat shield if ya can get one. S/steel exhaust (full system inc manifold) is always a good addition too :) (and yes I have both ;) ) Make sure you do all engine/performance mods before getting a remap !! Not too sure about a 150 quid remap tho,hmmmm,id want before and after dyno print outs as proof and personally Id want to see it being done !!
