My recommendation is to remove the blitz units and pipe up your OEM ones, the MAF metered system doesn't like vent-to-atmosphere venting. If you are hell bent on keeping the blitz's then you can remove the OEMs with the associated piping and install some snug vinyl caps over the inlets on the metal pipes or go get some plumbing pipe plugs and install them inside. I wouldn't just keep them as they are, depending on their shape they may be creating a leak in your system. Also if you're interested I'll take them OEM recirc valves off your hands, PM me with a price once you have 10 posts.

thanks lad for the info,i have one more quick question when i rev the car over 4000 rpm i just get over 0 psi,i thought it might be the boost gauge in the cluster but i have a aftermarket hks boost gauge,as in this video while idle i get the same boost but not while revving only over 0 psi,anyone know what the problem might be(btw i have fixed 14 boost leaks),Mate i am in ireland,Thanks all

Watched your video. I'm assuming you're talking about the boost not going over 0psi, and in that video, it looked to be building boost correctly. If your concern is about neutral revving, you won't build past 0psi generally.

Unless your question was about the oil pressure gauge, in which case it's more than likely the sending unit.

Ahh well in that case the shipping would probably be more than the valves are worth. Welcome to NICO, glad to have more international members. Ireland is a beautiful country, can't wait to visit one of these days.
