Last night I installed a Forge Performance adjustable BOV (recirculating) on my TSi AWD. It's base spring is 7 lbs.
A friend and myself were doing some pulls on an empty street so we could figure out the best adjustment for the BOV. Shortly after we got it dialed in, the car started making an awful "howling" noise under boost. No loss of boost, just the strange noise.
I checked for any leaks, including all FMIC piping. I didn't find any. I reset the BOV to full soft, same noise.
Anyone have ideas? I haven't checked for shaft play yet. I'm praying that's not the culprit
Only other mod is an eBay FMIC that came with the car. Everything else is stock.
