I am going to hijack here a little bit.I am putting together a 5.0 for my 96 bronco.The air pump removed,tube plugged,selenoids unplugged.Also installed gt40 intake from explorer.No throttle body yet.Do I need to install egr?Manifold is internal egr.I am going to have 2 o2 sensors on y pipe and 1 after bazani cat.Am I going to have problems?No phony evp.I read on RJM that I needed a custom chip to make this work.
