complete tun up

You don't. Tuning used to involve things like setting the timing, dwell/point gap. But now there isn't even a distributor to set or replace parts in. The cars computer does the timing and adjusts it as needed. So there is no such thing as a "tune-up" anymore. You also have a coil over plug system so no plug wires. the only thing you can do ignition wise is change the plugs. So much for a tune up huh?
