personally i'd advise you to go stage 3 mate,as by your comments you will always be worrying about your engine.thats not a dig dude,just seems that way to me.even though its as safe as any tuned engine can be.but then karl has spent many many hours on mine and tiff's getting it right
if you come to the essex meet tomorrow mate,i can take you out in mine
