Im having serious bov problems
BOV's need regular maintanance.......they need to be cleaned and oiled every so often to prevent problems like you are currently having. I remember with my sti the turbosmart bov would get stuck every now and again, I just took it off and cleaned the piston and oiled it. The turbosmart bov is one of the best out there, you just have to clean it.
make sure the vacuum line going the bov is not leaking, and also check the IC pipe and hose that connects to the bov for leaking as well... If these don't help, I believe there is an adjustable screw by the throttle body which you can tighten to help with the idle.

I have a JDM MR BOV sitting in my garage I could sell you. Send me a PM if you're interested.

03silverevo, there has to be someone with an Evo around you. You can't be the only person in the town with an Evo. YOu just need to find a stock BOV and slap it on. That will tell you right away without going through all this trouble. If you have to, just buy a Forge RS DV and slap it on, then sell the Turbosmart. Do something - talking on here won't fix it.

As far as all the lines i checked everything and everything is on tight and is on good. Ok take this into consideration. Say i go in first gear to the point to where the BOV releases the most pressure and if i put the clutch in after this the car either dies or trys to.

Well i had couple people pm me. One was about readjusting the Turbosmart. I turned it all the way to soft to where they was only like one thread left on the screw. Car seems to run a helll of a lot better. It hasnt stalled out anymore but the rpms are still droppin rreally fast like it wants to but it catches itsself before it dies
so you said in your first post you are running VTA... the turbosmart bov is a dual port bov and should be also recirculating at the same time unless they have the recirculation side blocked off with the metal plate.
I had this BOV on my car for over 20,000 miles and never had a problem just got annoying because it was so loud. I would suggest checking to make sure that you are recirculating back into the intercooler piping and venting out, because that would definitely cause some stalling if you are running straight VTA.

yes you have a dual vent bov, the evo needs about a 50/50 mix with the dual vents or you can stall and just have problems with the bov, if its running just to vta, yes your maf will not meter air correctly and have issues.
I have a APS dual vent and have not had the problems your having, running around 50/50 and yes it has stalled on me maybe once or twice in a year but i have it adjusted a little to tight, get partial throttle surge once in a great while as well because the valve is adjusted to tight, easy fix otherwise much better than stock bov on my o3 better boost response, or no stalling like the stock one was . to those who say at stock boost the stock bov is fine, mine was not, running only 19lbs max i started getting the stalling and not holding boost great and today is a great example. took off the aps bov(selling it lost job and car
)and put stock back on and it stalled after less then 5 miles. many evos have boost taper at high rpm, esp since you are running such high boost stock injectors may be maxed out etc...
recomend: adjust the bov for less vta, your running a lot of boost? still with stock injectors and head studs? ams suggest no more then 19-20 with stock head studs ask um! still having problems get the aps one tested up to 30 on thier site

Well it could be stuck open. The only way i can adjust this BOV is to move it from soft to hard thats it?? Unless theres another way? But right now its turned all the way to soft. As i said in my last post car seems to run better. But the RPMs are still falling fast enough to where it wants to stall out but it catches itself
