What does your boost gauage VAC read?

[jwfcms]

Simple question really, if you have one fitted what dpes your boost gauage vacuum read normally in HG? its the lower part of the boost gauge below 0 negative pressure. mine is around 19-20 on idle and when driving with no revs 22. is that normal what are all yours??

approx 23. With foot off trottle still at 23 and same at idle. Lightly press the accelerator goes to around 10 but thats subjective.
Boosts to around constant 14/15 psi (12 in second gear) - doesnt seem to peak higher either

mine goes even lower than 22 i think.. goes all the way to -30 but ive done the bypass so dont know if that would cause it

Turbin that shouldn't be at zero at idle. Should be reading a vacumn.
Where have you installed the tube?
Mines off the fpr.

mine sits about -17 on idle and about -21 when off throttle but moving.
i think vacuum is measured in inches of mercury hence the symbol hg, but dont quote me on that its been a while since i did chemistry
