I am not too sure about deleting it, surely it has a purpose  :undecided:

If I do that do I have to delete or by pass anything else ?

Just read Bav's guide to doing the N249 bypass, and looks fairly simple enough to do. If this doesn't work then I think I may just give up and save my money up from now on, and put it towards buying another more powerful but unmapped car!

It should be done anyway really if nothing else its one less thing to go wrong, I used this guide here:-

Thanks mate  :smiley: I see in that link he shows how to remove the SAI, while Bav's he doesn't recommend that is done, as he put his back on after taking it off. Plus I have had the rivets in the pump changed to bolts, as recommended by Nick at R-tech when he remapped my car. As that apparently stops the thing from leaking.

Yes it does stop it leaking if you do the bolt mod, I removed the SAI because the ribbed pipe that connects to it cracked and VW wanted something like £16 a section x 2 or 3 sections  :shocked:
I also use a CAI so didnt need to run the pipe into the Airbox

frees up loads of space in the bay, when I get round to it I'll do some pics  :nerd:

Bavs replaces all the standard tubing which is prone to breaking down and splitting with silicone tubing where as the link I posted removes the N249 and N112 and the hardlines are replaced with 2 sections of silicone tubing, one from the plenum to the DV and one from the plenum to the FPR

In short if it can go, on mine it goes  :grin:
