BOV leak?

[eclipsegsx1736]

I was getting on the freeway so I decided to give it some gas in 1st (almost floored), and at ~5850 rpm i felt the power drop off quickly (I didnt ease off until after I felt the power loss) along with a loud air/whistle noise. Im assuming this was the BOV (vented Greddy Type-S). Does this mean the BOV is too soft and i need to turn it towards hard? It seemed like it leaked when i got on the gas and revved it up pretty high.

The GReddy one shouldn't leak if you have it adjusted properly. If you are venting without MAFT or VPC, some motors will stumble causing loss of power symptoms.

yeah, i think thats the problem that it isnt adjusted properly. I just got it so I guess these symptoms are from it being too soft right? And how much should I turn it at a time?

T25's won't hold boost after 5500 rpm anyway, that's probably what happened. That's why there also known as the "T-too small".

Yea, they do tail off after 5500rpm, but they don't have that loud air/whistling noise.

How long have you had the Type-s on your car?

I bought the car about 5 days ago, and this time and one other time on the freeway ive heard the BOV whistling/fluttering when i step on the gas. Im going to try turning it towards hard soon, how much should I turn it?

I'd go little bits at a time. If it gets too hard, it won't release properly and you will get compressor surge. Don't be afraid to play with it a little bit, but be weary of a 'fluttering' sound. That means compressor surge and will kill your turbo over time.
