Default boost guage vacuum

got a quick question...

right now i have a godspeed bov and sitting at idle, the needle on the boost gauge reads -20, i switched it over to the turbo xs bov and it reads -10

is there a reason for this? when i use the godspeed bov, my boost hits 7 psi but when i use the xs turbo bov boost hits 5 psi?

confused

Cheap BOVs? Right now I'm using a Greddy knock-off BOV and a cheap Sunpro gauge and boost hits right where it's supposed to.

Sounds like a leak.

Huh, should still be pulling -20 even with a leak at idle, that is if you're boost reference is off the intake manifold.

thanks for the input guys...i took the top off the bov and found out that it wasnt sealing all the way, used a rubber o-ring and sealed it off, now it works like a charm
