Yes i will leave it unplugged. What does the vac advance do anyway? Better fuel mileage?

The motor does still ping under hard acceleration but that's because it's going lean. I've got a Innovate Motorsports AFR analog gauge, and a Holley 4150 double pumper. I just got the Holley, changed from an Edelbrock 1405. The Holley pretty much runs perfect out of the box except for hard acceleration. I've got a 50cc accelerator pump and bigger squirters on the way. I'm sure that'll remedy the problem.

Thanks for the help gentlemen
