Re: Vacuum Advance and why to use it on the street

Great question Eric. Fogive me that I don't know what the factory timing specs were on these engines. Did they have any emissions controls? I suspect I know why the VA may not have been utilized, but I am such a Day 2 guy that I honestly don't know how these were in stock form. I'll be the 1st to admit that my tunes aren't always the most "emissions compliant" as the OE's are required.
