Crankin, Welcome to the sight. I too had these questions. The tymare mod-- I made mine out of a 6637 filter and a 4" piece of exhaust pipe. I had added an ATS turbo housing that came with a 4" intake. What I am running is a ATS turbo housing that has a 4" intake and the big filter. The AIH delete is the Air Intake Heater. This is located just prior to the intake going into the engine manifold. As far as the wast gaite, I unplugged the red air line going to the waist gate. This allows me to go up in boost.
