When you do the EGR Delete, you remove the EGR cooler and link the water pipes together, but you also have to block a couple of the vac lines. This is why I did the vac line simplification and it is really easy to do. The thread on it couldn't be more straightforward. You don't have to replace the vac lines with silicone ones, they just look prettier. From all the ones you remove, you can just pick some and fit them instead. All I used is the threads on here to do everything, but then I am great haha!
Bump.For those looking at the other thread on this subject at the moment
