That is your fuel pressure regulator and there is an aftermarket adjustable version I've seen for the '97-'98 C5. The hose that plugs into the front of it is a purge tube that connects to the throttle body on the driver's side.

seems like the throttle body doesnt have the plug
i can't remember if was pluggled into the stock air bridge,before the superchager bridge
the only thing that i remember is that was a black plastic line,but i cannot find the plug =(
That pressure regulator plugs into the side of the stock rubber air bridge, just ahead of the throttle body. It didn't do much, the more vacuum the tube applied to the regulator, the lower the fuel pressure was. Seems to me it would only operate in a WOT condition with an air filter that was partially loaded up not allowing a full flow of air, it would then cut down on the fuel pressure some.

and now where do i plug it??
is it ok if i leave it unplugged??
on the ATI manual doesnt say nothing about it!
I'm not sure if it will work properly in boost or not. It is a vacuum tube to reference the fuel pressure to the manifold vacuum pressure, but I doubt it is meant to work at a positive manifold pressure. If it is disconnected I would imagine that the fuel pressure will just remain constant and you would need to just tune the car accordingly.

if i put an adjustable pressure regulator,where doi have to plug it????
cause seems that i need one to tune with the SC
