I'm still a newbie to bov's. Can someone explain to me why my revs jump up while shifting? I know it has to do with the bov because it just started when I installed the Greddy type-s. At first I only turned the adjustment screw 3 full turns and it did not happen, but boost was not holding???? So I tried to tighten the screw and now the revs jump up only when getting on it. By the way I still don't hold boost. I have a Greddy profec b spec II so I know I need to mess around with the tuning on that as well. For now my concern is holding boost 20-21 psi and not having the revs jump. Any info would help thanks.

 

You sure all the vacuum lines are tight ?

 

After the meet we had tonight it all good now. And John if you read this I get the boost to hold at 20.5 in 4th and 5th all the way. Now I just need to find the right setting for 1st through 3rd. I still wonder what caused this in the first place? Anyone have a clue?

 

i can't beleave you started a thread about this.problem fixed.i don't no shat about ebc.start another thread

 

That what these forums are for

 

the the greddy type s.... I hate them for the evo~ all the spring mods you have to do, just buy a blowoff valve that is compatible already with high boost. Step it up to the greddy type-r best blowoff valve i've owned... and its quiet

 

Ok I thought this was fixed, but it's not. It still jumping up in rpm's and now my cel is on. Can anyone help me out with this?

 

WTF!?

 

My cel had nothing to do with this, but I still can not figure out what is wrong with my car. When I boost and then shift my rpm's jump about 700 rpm's and then fall off until I push on the gas. Had anyone ever heard of this? I have tried everything with the bov. I may just go back to stock or get the HKS.

 

As I continue to try and solve this issue I may have it fixed. I put both springs in the bov and now the problem is gone but now it flutters. I have the screw pretty tight so I hope the flutter will be just about gone with the screw almost all the way out.
