hi article in auto italia september 2004 for these via a tunit box a proper set up claimed 207bhp and a wopping 340ft lb if you need more than that get a mandrel bent outlet to turbo exhaust and quickest mod is to take that cat out as diesels don't need them 4 mot!!! but the box alone will eat cossies i've seen it done and it was 4 log books so lad lost his cossie lol
