Haven't done a lot to the AU yet, just a K&N panel Filter, spacer on the inlet manifold, got rid of the mufflers, just the resonator on the back (its got through 3 mots like that now ) Had it re-mapped by Adam at SCT (He's got a nice F6 Typhoon) I've also got a set of Pacemaker tri-y headers on the way that I ordered when I was home last month. Still don't think it'll get anywhere near 400bhp without a blower though.
Did you bring yours in yourself? I thought they were making it a real pain these days.
