Hi, I'm Earth. Have we met?
IMO I would recomed a Edge Juice And a Kennedy Diesel Boost Stick . The juice will give you full adjustability in power and the boost stick will keep the egts from the added power down!!!! As for the intake they dont offer much improvement if any! and The exhaust i would do a full 4" system with a cat delete pipe but if you go with the cat delete pipe you will also need a code blocker to keep egr codes from setting!!
