Rep Power: 0

About a week ago, I started noticing that it felt like I was not getting the same power when boosted. My BOV used to make a loud noise when (the good noise) when I used to let off the gas at anywhere from 2 -8 pounds. Now, I can only hear the BOV when I release at 7 or 8 pounds. Plus I only feel the gain at 7-8 pounds. Don't really feel any difference when at 1 - 5.

Also, when in boost, it sounds more "airy", if there is such a thing. Like I can hear the air louder. Any suggestions on what it might be? All of the vacuum lines checked out ok. A friend of mine said that, since it is new, maybe my BOV spring, after getting hot, has started to tighten up (or loosen up), and I need to adjust it. Maybe loosen it up.

Any suggestions? Oh how I miss the "PSSHHHT!"

When I had that airy sound it turned out I had a nice hole in my charge pipe, worth checking it out.

That would really suck. My charge pipe is hard to get to. I would have to take it apart to do so. Loosened up my BOV. Sounds a little better. Still "airy" sounding though.

check all your pipe connectors for tightness. sounds like a small boost leak somewhere.

I'll do that. At least 3 of them are not accessable unless I take everything apart though, and since I didn't put it together, I doubt I'll do that. I can live with a little leak as long as it doesn't hurt anything.

just check it out so your car is running with more boost. It shouldnt be too bad to tighten it all up. You should just need a flathead screwdriver, and possibly jackstands and a jack.

yesp. check all the piping. my charge pipe pop/blew off the tb, like once / twice a week. I end up putting 2 clamps to tighing it.
