I had a problem with my VAP Windstar fitting properly. The intake was making a really loud noise, and my hood would not close because it was hitting the TB. The guys at Cisco Built Rides in Raleigh NC spent a lot of time figuring out what was going on.
The TB spring was pushing against the V spacer which caused the TB not to seal properly and raised it just enough so the hood would not close. So they ground down the V spacer just a little which allowed the TB to seal and settle properly to stop the LOUD whistling sound and allowed the hood to close. I have read where a lot of people have had problems with the loud noise, maybe this can help resolve some of their issues.
