Thats a good point about "tuning", "set up", and "modifying", and the differences.
So lets get this straight.
Would I be right in saying that "modifying" is the act of replacing parts with different parts in the hope that the car goes quicker/goes for longer and creating a car that is not box standard?
And "set up" is the act of making the existing standard parts work better with less friction and wobbles but ultimately not altering the appearance of the existing box standard parts.
And "tuning" is the act of physically altering the existing standard parts to make the car go quicker/last longer whilst staying within box standard club racing rules.
If this is so, then "set up" is not a problem for anybody as we all want our cars to last longer and run smoother.
But "tuning" is in my mind rule bending and straying outside the spirit of box standard racing and is cheating.
And "modifying" is clearly something to be done where rules permit non standard parts and goes beyond tuning and is not an issue at an event that allows it.
It is the "tuning" thing that I am not keen on as it is race fixing.
It is of course possible to apply "tuning" when "modifying" so that non standard parts are altered to gain advantage.
This is all very murky stuff.
The web sites refered to above don't really make it clear what is murky and what isn't. Maybe they should.
