Guys,

I am still tinkering on my Charger and I am curious if I should once again hook up the distributor to vacuum or not.

The backstory is that when I had my car dyno'ed a few years ago, we found that the engine pinged at WOT (still does on warm days) so the dyno guy said to just leave the distributor disconnected from vacuum to help fight that. It has been that way ever since.

Right now the engine is at 16* initial timing and it advances to 36* total by 3000RPM's or so. This is with the dizzy vacuum plugged.

Would I gain anything by connected the distributor back to manifold vacuum? I know that the ported vacuum is more of an emissions thing as it kills the high vacuum signal at idle. If I use the manifold vacuum, will that improve my idle by advancing my idle timing further or am I just wasting time here?

Thoughts?
