I should have explained myself.
What I was trying to say was, if the stock BOV is working fine, there is no need to replace it.
"If it is not broken, don't fix it".
Myself and a lot of other Skyline owners on SAU are strong believers that the OEM BOV from Nissan has a very high capability and will rarely need to be changed.
Having said that, it is Chris_GTR26's car and he can do whatever he wants.
+ I am sure through your research and development, your BOV will perform well too, as what you have stated in your post.
I should and will retract my comment in saying your BOV is "inferior" as it was said out of frustration as SAU sees a lot of BOV threads, which end up in a pointless discussion / shit fights / a modification that is misunderstood at times.
I am in no means to talk down your company and apologies if you felt so.
