Thanks guys. So I guess mine is fine. Does yours drop to around 600 when shifting. Mine drops that low and then comes up and idles around 700. Is this ok?

 

Are you venting?

 

No way. I have it connected back to the intake. Why?

 

Because venting can cause that. Is your BOV leaking?

 

if ytour car isnt stalling its fine, it sounds like you just need to adjust your biss a bit.

 

But to adjust the BISS, it requires a special tool, right?

 

ya a phillips screw driver lol.


you very well may have a smakk boost leak somewhere i agree on the idea sebba was thinking

 

Actually I dont think its the BOV. I just put in a Greddy Type RS BOV. But I will check it just in case. So all I need is a screw driver? All I have to do, is give it a turn, right?

 

Yes you turn it till it idles where it should (Recommend doing this AFTER the engine is warmed up and set the idle to approximately 750 RPM).

 

My EVO idles at 850 (acording to my SAFCII)

and after adjusting the BISS screw if you still have a prob between shifts and with idle then you have a boost leak , which is likley the BOV if you just installed it and the problem started
