Advance engine tuning will require increased air and fuel delivery for increased power output. Since this will exceed the stock injectors the requirement to upgrade is a necessity. Increase fuel supply is generally required with almost any upgrades from increasing boost to camshafts to turbos or other forced induction means to allow the increased air and fuel mixture required. TOMEI has the right injectors for the right job on the engines that we specialize in.
