Iv read through the guide but im abit stuck. Im in the middle of removing the sai combi valve, im getting confused with where the dv pipe goes. Am i right in saying i remove all 3 hard lines and connect the pipe on top of the dv to the bottom of the intake manifold. Iv ordered 4mm vacum pipe like a few ppl stated in the comments on the guide. Is this the pipe i use from the dv to the manifold?

Yes that sounds right, 4mm I/D piping,

Ok thanks. Is there any pipes that need blanking off?

From what I can remember 2 ports on inlet manifold join them up with a piece of your 4mm pipe, and one on the TIP
