After a chat with one of the local coppers I have decided to change my BOV before I get more than just a warning next time.
I have a r33 rb25det with a gt3040 on it running 18psi at low boost and 25psi at high boost. The car had on it a blitz dd bov and if it wasn't a daily driver id keep it on. The car drives fine, I never had a problem stalling. I am running a link ecu so now afm tho. My question is what plumb backs will be able to flow the 25psi from such a large turbo? What are others using for there high flowing plumb back systems?
Thanks for your help with this guys and also for not jumping on the flamewagon.
