I know alot about bolt ons and a little about performance engine building but next to nothing about computers and chips for cars. I put a new Pro-Flo 75mm Mass Air on my 92 5.0. I hear your supposed to add a chip. What problems might arise? Also, to do a custom chip does the engineer have to have your car? If so does anyone know of a reputable place in Georgia? Any help would be apprieciated. Aso can can think of anything I might need to know.
