:in a straight line besides injectors(run more boost), dual pop(breathe better), and turbos(push more air into engine). Those of which are not that cheap either. :good injector kit $1300 + $50 for ash reprog ecu + some AN fittings and braded line to connect rails to make kit complete :doolz $225 + $50 for ash reprog ecu + $90 2nd pop charger :turbos have a vast price range... :maybe start looking into some suspension pieces thanks
