A Good Tune??

"Good Tune"

Could mean
'Change the plugs/cap/rotor'

OR

'Custom ecu re-program using a J3 chip'


Maybe a little clarification would help narrow down the question?

EDIT:
My point being that the phrase 'Good Tune' is grossly over-used & mis-used on the Mustang sites.

I was just wondering what people meant by a "Good Tune"? I consider a tune up to be changing plugs, wires, rotor and cap, air filter. Maybe someone else thinks different?
