I don't think you can fit a dump valve straight on a diesel because there's no vacuum from the throttle body. You need to make up a vacuum system you might need to google it or someone here will defo know. As the box if you want good cheap one from eBay look at tdi tuning ones for around £80 but for the best results your looking at a remap egr delete and catalytic converter delete also. I have a little knowledge on diesel tuning but I think that May give you some scope on what you need to start out.

Ah right I just thought I would possibly be able to fit a dump/blow off valve straight on to a diesel, hopefully someone will know for definite though. http://item.mobileweb.ebay.co.uk/viewitem?itemId=181301006456 that is a link for a tuning box I have saw do you know if that would be suitable? Thanks for the reply
