You sure? It looks like it goes down to solenoid D (EGR).

your car wont have EGR. If it does go down to EGR ( i cant see clearly enough in that pci...shud have gone to spec savers), then just cap off the nipple on the plenum and you ll be fine
EGR is for us spec cars to help them thru emmisions

Have you got a performance downpipe ? And you are using a boost controller ? If yes to the downpipe then that could cause overboost.
