Rules are Rules, you must abide by them blah blah. I understand. I am not going to break any rules and I am not trying to whine about anything. Lets have an intellectual discussion on why or why not the rule could be or should be changed.

Replacing the unit with a better one will still retain the emissions functionality. I am having a hard time seeing how you can extrapolate this issue into a modification which replaces the PCV valve that creates an overwhelming advantage. Does anyone have any ideas how you could replace the PCV and gain a huge advantage? Like stated before, you are not even allowed to run higher boost levels anyway.

Simply put, a PCV valve replacement should easily be allowable. If you can upgrade exhaust pieces for increased flow and better power in this class, then doing a mod that has no effect on emissions, no significant effect on power, no effect on chassis stability... it should be a no-brainier.

From Crawford themselves:
"This not only keeps the vehicle within specs of smog but keeps the oil from coating the tops of the pistons. We all know what that does to any tune you have; it causes detonation, a very bad thing for turbo engines."
The PCV is removed and the port where it used to be is plugged. The AOS doesn't not "replace" the PCV, it's "added", as the AOS can serves a different purpose. (it's not a valve) Replacing the unit with a better one (assuming you implied AOS) will *not* retain emissions functionality. Please read up on how a PCV works.

Crawford may advertise it as keeping in spec with smog, but the reality is it's not 100% the same. You are correct in that it will not create an advantage, however that's not the point. If you change the rule, there are other cars within the class that may be able to take advantage, etc. It needs to be looked at from all angles, and the point of a class is to prep your car to that specific ruleset. If you're just running locally, like others said, just go out and enjoy your car.

I'm all for reliability mods and would agree that it should hopefully one day be legal. However I'm an ASP guy who just butted my head in here when I saw the words "Crawford AOS". Luckily I don't have to worry about that restriction in in *SP.
