running no vacuum advance

I have not used vacuum advance on my distributor for going on 4 years and my car runs just fine.There is no difference in plug life and no noticeable difference in gas mileage.I tried the Crane vacuum set with the cam to limit total timing,the car had an Accell adjustable vacuum can already on when I bought it.No matter what I tried there was always an issue with pinging at part throttle tip in.My buddy convinced me to try it without any vacuum,he doesent use vacuum on his Hi Per small block either.No more pinging at part throttle tip in,car works better than ever ! I think that just because something works in some situations doesent necessarily mean that that is the answer for everybody.If,in your application,your car works better without vacuum advance hooked up,leave it unhooked and enjoy it.
