Attention '05 Evo and MR owners
alright lets get some more people to confirm this, i want a BOV that can VTA but with no problems what so ever. this is the only reason i havent purchased one yet.
No proper way to do it unless you run a True MAP system, via a stand alone. Otherwise, any bov that vents into the atmosphere will vent metered air and your car won't know it.
You can also purchase a blow through MAF and move it after the BOV, that'll work fine as well.
I am running the GFB (Go Fast Bits) Stealth BOV also. It is set at 75% no problems yet. Has been on the car for 3-4 months and this is a daily driver. It is nice cause if you keep it under 3000 rpm it wont WOOOOOOOSSSSSHHHHH at you. It is fully adjustable as stated earlier just not as loud as I would like. Would really like if I am sitting at a stop light, rev and blow off, and the people walking or/ sitting at the bus stop makes their hair move. my 2cents.

MAP sensor on left, IAT sensor on right.

so, someone said that you are ****ing **** up if you vta, rather than putting some of that air back into the intake, is this true? anyone who really knows what they are talking about have something to say? i just bought an agency bov, just got it in the mail, it has a dial to split how much vta, how much back into intake. but i'll just run it full vta if it's not a problem, probably get a higher noise that way huh?
