Thinking of putting a chip on my 3.8. A couple of questions first... with adding a chip it's going to change ther forformance and "appatite" of the engine. Is it necessary to change to hotter pulgs add a coil pack install larger feul injectors and add a high flow fuel pump? Or am i just going overboard?
