    can you go lower or higher is there a big difference i read this chart allready but i was going by ferchos carb assembly and he's using 1.5 n&s ang 115g spring and it says hes aiming for 45-50 psi and according to this chart for 1.5 n&s and 115g spring it should pop-off at 55 psi

    The readings in the chart are with a calibrated gauge. Not may people have a calibrated gauge. And it also depends on your altitude as to what readings you get. As long as you are in the ballpark you will be fine.

    My suggestion - go with 95g springs and about 42 psi popoff.
