Difference between a "tune-up" and a "tune"?
I don't know a lot about this stuff and just don't know if a "tune" and a "tune-up" are considered the same thing. When I bring my car in for a tune up, do they even touch the pcm programming etc?
they won't touch your pcm at all.
tune is where they hook up a computer to your pcm and mess with air fuel ratios and such to program your car to run well.
