Well i have installed my greddy Type S BOV. And i have to say.... WOW! The thing sounds and performs amazing. Of course i have to tune it a bit more when i get my boost gauge so i can have it hold all 19PSI. But i recommend this product to everyone. I do VTA, and some people have said that when they have VTA thier greddy they get a Check engine light. not me. I believe because when i first installed it, i recirculated it, then went VTA.

 

How does it sound with the recirc? doesnt i sount like a muted whoomph or a softer whistle? DO u have any stalling issues VTA?

 

when u recirc you can barely hear it unless you have a open cone intake. But with it off it sounds incredible. i went to the track and people were like wow this wow that. Especially after i ran a 12.99 on a stock EVO. The way i reccoment to install it is to first recirc so the ECU dont toss a check engine light at you. And you if you are riding and you come to a stop without reving down i will bog and possibly stall on you. But i hear there is a spring mod for that. But you can just adjust to reving down to a stop instead on just pushing clutch and rolling into neutral to a stop. When it VTA it like a nice whislte with a wooosh.

 

12.99 on stock evo with just a greddy vta tybe s bov.hmmmm....

 

I tried to VTA my Type-s, then I had CEL issues and a poor idle, So I recirculated the BOV and it still sounds like it is VTA.It;s awesome. I do have a filter and piping kit though.

 

Anyone else vta with the greddy type s? Any problems?
