81 plugged EGR
 

Last night I replaced the emissions and EGR hoses on my engine and I noticed the previous owner had plugged the EGR valve hose.
The A.I.R. / smog pump has also been removed.
I removed the plug that was in the EGR valve hose and replaced all the hoses to the way they are supposed to be routed according to the routing diagram on the inside of my hood.
My question is this: Does plugging the EGR valve hose improve performance?
I have read different theorys on this and I wanted to get your take on it.
Having no emissions testing in Florida I'm not really worried about that.
However I do want my engine to run at it's best performance.
So should I put the plug back in the EGR valve hose or leave it out?
Thanks for your input...
