I installed the Greddy type S BOV but by redline the psi is droping from 20psi to about 16-15. any ideas why it could be doing that? i have a hallman pro mbc installed as well. the stock bov was holding fine til redline. the bov has the singe spring in it. could that have somethign to do with it? if anyone knows what it could be let me know.

Did you put the vaccum hose on the wrong part of the BOV?

 

no the vaccum hose is on the right way. i looked at pics of it installed on many cars and its done right.

 

i just installed mine and it feels halla slower. i hooked it up like the photos and im running the single big spring and my sh it sounds quiter then stock even if i turn it countclock wise to hard i dont fell a differance. im not sure if its turned out far enough, i dont really know when it hit the perch inside. i know im not suppost to gain power but **** i cant lose any! ill keep trying it and well see.
