Call me an "old fart", but back in the late 60s, when I first started working on cars, a "tune up" consisted of a new distributor cap and rotor, a new set of plugs, a new set of points with a condenser, a new fuel filter and an air filter. Plug wires went for 2, sometimes 3 years, depending on the mileage.
OK, I realize that today's cars with electonic ignitions don't have "points" anymore, so scratch them. However, the electronic ignitions throw a LOT more voltage than the old point type ignitions, so while the plugs become less critical, 'cause all those extra volts will fire them, everything else becomes MORE critical, because of the extra volts they are required to send.
To answer the original question, what would constitute a "tune-up"? I would say cap and rotor (on an LT-1), plugs, wires, fuel and air filters, and a good dose of either Chevron Techron of Red Line fuel system cleaner. And, while you're crawling around the front of the engine changing the car and rotor, if it's an LT-1, maybe a new alternator belt, for good measure.
