After putting Mac long tube headers, mac h-pipe and flowmaster cat-back my "check engine" light came on and constantly comes on after a little driving. An OBD1 said i had improper fuel ratio. The guys at the auto store said a chip would correct this. Would a Jet Powertech Performance Module do the trick? Or should i get a superchip or Hypertech?
