Manifold Vacuum Experiment

Aight den. I have an update. I can tell beyond a shadow of a doubt the engine idles cleaner. By a good bit. It also has more balls at part throttle pulling up inclines. A lot more, actually. No spark knock whatsoever with the can turned all the way clockwise, so I don't think any adjustment is necessary there. All in all I think this was a beneficial mod and I may revisit it on Vixen. I didn't put the vacuum gauge on it but I will in the coming days.
