My point was, that the car won't handle as well as it would with a real tune. Also that there's no possible way to get shock settings, that could translate into GT5's boundaries, or LSD for that matter, or ride height. (This is not the fault of the tuners, nor people interested in replica's mind you.) Simply, that what people do with these cars is outside my comprehension of enjoyment, but I won't discredit anyone else's enjoyment, as it has no effect on me. Play the game as you desire, but to me, there are rather useless, as they serve no point within my playstyle.
