You would do well to remap the ECU for any intake regardless of what the manufacturer claims.

Why are you installing a different BPV?

I would HIGHLY recommend that you consider functionality before sound.

That being said, an SRI will allow you to hear the BPV a bit more, but you will need an ECU mapping solution. Today, your only real options are Cobb and ECUTEK.

I'll be honest with you -- the "BOV sound" is super ricey. That's a whole lot of money to spend on something so vane.

Has to be tuned for the intake. This topic has been beaten to death.

There isn’t any reason to install an aftermarket bypass valve, it is a complete waste of money and effort.

I replaced mine with an aftermarket unit because the stock one was leaking. You can't even notice I have it.

True I misspoke that is a reason. In general there is no reason to replace a functioning bpv on a stock car.
