YO! I have some problems with my boost gauge, maybe not my boost gauge.
It only reads 16 PSI vacuum when my car is at idle. It read around 19 PSI before i installed my BOV. I changed the hook ups abit for the boost gauge, but i dont' see any leak or anything. I actually re-do the hook ups again just to make sure. But it still reads only 16 PSI at idle.
But when i am driving, and i let off the gas it reads 19 PSI. once i step on the gas, then it changes. Is there something wrong with the FPR?? or something wrong with my boost gauge hook ups?? let me know plz ! thanks !!
Also, it does read 5.5 PSI with my greddy turbo kit when i boost ! hhe.. i finally start boosting

 

its not 16 "PSI" when its in Vacuum,its 16 in. Hg,thats about right for idle,and 19-20+ in hg when off the gas,slowing down in gear...your gauge is right,you just aint reading it right.

.

 

hehe ok thanks !
u r right!
thanks !

 

my car reads 20 in Hg. at idle almost 21 and when is rolling down it foes to like 25 i thick your bov needs to be checked for leaks 19 sound more right check for leaks agian my bro has a lumpy idle and he eads about 17-19 at idle.
hope this helped latterzz

 

Can somebody give me an accurate answer???
my bov has no leak, coz it works fine when i boost, so i assume there should be no leak??? coz it reads 5.5 psi when i boost...
