that is great tip, I guess thats why mine liked it when I lowered the top advance. Will check out what I have at vacuum. As a matter of fact I did notice the vacuum reading was very good for my cam specs (around 17 inch vacuum at idle), but atributed it to the fact that I put an "serious street/mild race" cam for a 360LA into a 426 stroker. I had to load a much larger map and a high acceleration pump value (over 90% for a few seconds) to get the fueling part right and avoid it from leaning out. but at the end it ran nice, check out the video below:
I will check the reading at full throttle to see if its adding the vacuum advance to the theorical acceleration advance curve to see if its doing the same as the black car.
