If you fit an aftermarket recirc valve, like Forge 007P, you can bypass the N249 as this backs up the stock valve. It give the Forge valve a slight woosh when you lift off. Don't do it if you have the OEM one tho as it is known to fail!
SAI is used on cold starts to inject air behind the exhaust manifold which mixes with the fuel-rich exhaust (timing is advanced for 100 seconds on start-up) to get the cat up to temperature quicker and so reduce emissions. Removing it just makes the engine bay less cluttered.

Cheers Kriso thats cleared a lot up, I think first port of call is a dumpvalve then, cheers Damo ill have a look at that and keep it in mind for when i get round to doing it. Im assuming you both have your cars re mapped any idea of whats the best to get? I was considering Superchips because its close by?
We both are running custom stage 2 maps by P-Torque
Both of us have also had they stage 1 maps and they are very good.I would stick with the big boys that sponsor this site. The likes of P-Torque, REVO, Custom Code, Jabba, AMD etc.
Where are based at?
