They are also known as killer valves, more so because people just put them on, whack up the boost and say wahay this is great, then bang!! piston melted.
As said fuelling needs upping to suit increased air flow, I would save up for a chip, vastly better they really do wonders on diesels.
You can put the induction kit on but it isn't a limiting factor, so won't do anything, might sound a bit faster.
