Super tuning car runs good shooting for great

That's good. I didn't mean to imply things were not done right, just trying to help figure out how deep you might need to go to get your answer.

So you said in regards to the timing, "It comes in fast and I'd like to get aggressive with the vacuum advance if I could find the right can."

Have you tried backing down the initial to 16 and see if its what you're looking for? I do think you may have a little too much initial timing for V.A. to be truly effective here, it makes your window very small to get it right. If you had like 10-14 it might work better.
