GMC SKI

I was just wondering if anybody had replaced the stock ati blow off valve, with something better and quiter.
Mine feels like it is leaking boost when it needs to hold it ?
Is there anyway too tune it ?
Any sugggestion would help greatly

How much would that race blow off cost??

Also what kind of sound does it have to it, I don't like the high pictched chirp..

I would just get ATI's Race Bypass, the BOV that comes with the kit is junk, and actuslly, is a ford part, if you look at the numbers on it, you'll see the "fe" there, yup, ford junk. The Race bypass is made out ou billet, and is a way better piece, kinda live a valve in your cylinder head typr setup, it seals way better, and doesn't release the air out a small hole, it is open all the way around, so as to distibute the air, and the noise better, i'm putting one on my Turbo setup, they are an awesome piece, there was a guy on here that posted pics of his when he got it in the mail.

I will be going with a vortech bypass valve. Cheaper, and does the same thing.

It flows more than you can use.

From the import guys that we get in, it seems like the bigger the Blow-off the less 'chirp' it has to it.

I have had the ATI race BOV in my garage for awhile and will install it soon. I hope it is loud compared to the stock unit which I can barely hear.
