Holley stumble trouble

Are you trying to get some economy out of this car?... When I had one on my car I plugged it but now my MSD doesn't even have one on it.. I was wondering what benefits you were looking for having it?..
Besides this stumble you're having lol...:poke:...
No reason not to try to get the most out of it, right. If I get to the point of madness dealing with this stumble then I’ll surely just disconnect the vacuum pod and continue mission.
