Yeah, Porny's the man. The kit he does is very well made and he's v knowledgeable too.
Unbeknown to me, my egr was beginning to fail before I removed it (Porny spotted it on his laptop but you couldn't feel it) and my fuel economy improved after fitting it quite markedly. It's more a reliability mod than a performance one (Then again Porny's yer man!). There are no disadvantages to it in the real world, so it's a no-brainer in my book for what it costs.
Hope this helps!
