On some days when the Atmospheric pressure is very high like yesterday I am pulling 24"-25" but on other days when the pressure is low I am pulling only 21"-22". and on some days I am hitting 26"-27" It seems to be all over the place. Is there really that much of a swing in the vacuum gauge vs changes in pressure? Granted we haven't had any good runs yet but just curious.
