Then they should think twice about their motives and reasons for modding the car. When you get to the point of needing a tune, you're already getting fairly deep. If you're just looking to wake your car up and be done with it, then a PCM is a good idea. But if you fully have the intention of continuing to mod your car a tuner is a no brainer.
Not exactly correct.
These same guys telling you you should tune yourself are the same ones asking tuning questions on other forums.
