So I wanted to modify the engine on my jeep I was going to put a 505 performance ported head and a comp cam upgrade to the engine do I need to change the map curve for my engine or would an ignition piggy back work just as fine ? My jeep is a 1995 obd 1

depends on how much porting and how aggressive of a cam you're installing. sometime the piggy back system can compensate, sometimes not.
