why am i leaking boost??

[X-RATEDeclipse]

ok, my boost gauge goes up to 15 psi, but than will leak down to 11 psi. my brother told me bov could be broken, cuz when we took off that lil tube that runs from the bov, there was air comin out of it...

some help me

your boost will only hold for so long on the t-25 and then will gradually decline. i think the boost only holds to around 4500-5000 rpms then it will decrease.

what kind of bov do u have?

 

[X-RATEDeclipse]

stock, im gonna put a 1st gen on it tho

well there u go the stock bov is crap. it will leak around 10 psi. once i changed out my BOV (to a greddy) i was able to hold around 15 psi steady. still though the t-25 only holds on for so long and then dies down.
