A few questions regarding vacuum for my car specifically (since I have a mild cam)
Is there any one spot that would be more preferable than the next to take a vac reading from?

When sticking my mityvac to the boost line (off of the map) it read 16 inches with a minus 1 inch flutter. Meaning that the needle fluttered very rapidly between the 15 and 16 inch mark. It stays there. Is this good? And say it was just for conversations sake. Is that any indicator that I don't have a vac leak anywhere else? Or can I draw a good vac reading from one spot, but still be deficient in another.
