well i had a blitz supersound bov, sounded funny to me,,, makes a ch ch ch ch chhhhhhh when it blows off, changed to greddy type-s imitation and its still making the same noise, figured the sound at least would be different.... how do i fix this, this is compressor surge right

 

prolly, it sounds like a deep flutter.

 

mine does the same **** but I think its the bov fluttering since after the cha cha cha i han hear buzzzzzzzz as the turbine spools down out of my open DP, so im not sure it actully is compressor surge

 

switched the vacuum line it was going to and it seems to have fixed the problem

 

what u mean, just went to a better vaccum sorce?
I got mine all hooked up to a GE vaccum manifold but i think i ned to incread the size of the drill hole
