Mine, with stock reg was 35 with vacuum line attached, and 45 
with out vacuum line. I get 17-20 mpg city/road. After I installed
the ATR adj reg, I moved the pressure up to 40, with vacuum
line on, and MAN, I could feel a nice HP increase, must
have really been too lean at 35 !!

yes, but after you know the diff, I would just always
adjust it with vacuum line on, so that you can reference
the change in pressure vs performance gain.
