just crush the stock bov and you shouldnt have an issue.. or upgrade to a tial bov all depends on your budget

 

Crush it a bit. It is free and takes about 10 minutes to do everything. I just did that to mine, holding 28psi without issues.

 

For my 2c, I've been very happy with the Synapse Synchronic BOV. I have a BBK-Full and stock MAF. No flutter, recirculated, and easy to install.

 

are you running port a & b?

 

OP, ygpm

 

Yup, A & B with the two port Evo specific version. It's a very large BOV, so the fitment requires a bit of jostling, but it works great. It's also very loud, so despite being recirculated it sounds like its venting to atmo.

 

Anyone try the Tial QR yet?
