EFI’s great but I still love watching guys read spark plugs like tea leaves

Modern data systems are nuts. They know every microdegree of timing, every psi of boost, can even tune live by track temp. But nothing — nothing — beats watching a crew chief with nitro stains on his hands pull a plug and decide, “Yup, needs more weight on the clutch.” That’s racing. Sensors can tell you it’s wrong, but only a salty old tuner knows why. #NHRA #DragRacing #EFI #OldSchoolGear #EngineWars
