Stock 91.. curious if I get an aftermarket BOV will I need a tune? The stock BOV is stuck open.. I can’t find much information on it are BOVs generally universal? If you have sound clips of what you’re using that would be nice.. also can I use/what brands should I go for on stm tunes since that’s the only place I can really find them for saleIMG_6940.png

I'd just try and find a stock replacement. Even a crushed one can hold a decent amount of boost.

I figure if I’m going to change it might aswell upgrade.. I found out you only need a tube if you’re blowing to atmosphere but Tial makes a bov that links right back to the boost line

Make sure it fits the stock BOV shape. Or, you might have to have another mount/adapter welded on too. If you are stock, you won't need a BOV upgrade for a long time. A WTB ad here or Ebay search will get you back on the road quickly.

Stock is fine. Back in the day, I ran a Gus modded one for awhile. The OGs would know what I am talking about...

Any that recirculate back will work well. Just get know brand one from a reputable place as there are tons of replicas that are not very good. I run a Greddy Type-S in my GVR-4 and a Tial QRJ in my Evo IX.
