I have full turbo back catless.. and intake.. installed a MR BOV.. All piping and plumbing is tight and leak free.. Car runs strong and healthy.. No Ecu tune yet.. When i accelerate in first or second and then quickly push the clutch in the rpms drop and then instead of stabilizing they go to low and unless i feather or catch it with the gas.. the car stalls.. has caused me some driving issues esp in intersections. I know others have had this.. Some say its the short intake and the maf sensor screwin up with the BOV releasing air into the intake..others say its because im untuned and have everything opened up too much for stock..

Any Suggestions..

thanks

 

Mine just started do the exact same thing.

 

lack of backpressure maybe...

 

I had similar problems after I installed the MR BOV. I know that some people are running theirs trouble free but I went through several different trials with different diverter valves. Each time the culprit was the MR valve. I finally came upon the type-s and even though it sounds obnoxious, it does the job and I no longer have the stalling issues I once had with the stock and MR valve. Your problem could be different but it is worth looking into.

 

Yea.. it did start making the most problems when i put the mr valve in.. But the MR valve works so great.. that stiff spring is awsome.. But it is really touchy on the throttle.. Im thinking if i do a little 50/50 by Go Fast Bits or Works i can fix the issue im having.. But i hear of others having the same issue with other setups. Im thinking of adjusting my idle up a bit to help the situation..

 

Maybe the HKS EIDS will fix your problem?

 

Just doesnt work in your car. Do you have an HKS or AEM intake? Open element?
The MR doesnt work on my car either. Check this:https://www.evolutionm.net/forums/sh...ghlight=mr+bov

 

get greddy type s or APS. You wont ever have a stalling problem or low idle again.

 

So why doesn't the MR Bov work good with HKS RS intake, I am currently looking for a new bov right now and I was going to purchase the MR but now after reading these stories im having 2nd thoughts. I see some of you are recommending the greddy type-s but i thought people had similar problems with that aswell, stalling and whatnot.

 

That's probably what I'm gonna do...install the EIDS and go from recirc to VTA...heh heh...like it isn't loud enough already!

 

Like one guy said: "if you just get an intake and BOV, your car might feel a little lop sided". What ever that means.
