Removing the overboost indication and EGR

[monkeh]

Got a 940 d24tic on its way, Its got EGR. I have a non EGR manifold, and intake Tee piece, but I understand it all ties into the overboost valve? I intend on elevating boost with a manual boost controller at one point so I would like to make it ready for boosting. Do I also need to set up the wastegate?
Ive had 2 years off from the forum/d24's in general so my knowledge is a little rusty.
