I got my other issue resolved regarding car dying and not wanting to start/idle/drive. I was able to complete a BLT and found a major, major leak at the BOV (not the gasket where it mounts but the actual valve inside) with as little as 2 LBS of air. It's a 1G BOV and is slightly crushed.

I've been experiencing hesitation getting into boost (if I let off I can get back on it and it will pull almost like normal) as well as I can usually cruise around at around 15 vacuum and start accelerating but now it's more like right at 0 vacuum/into 1-2 lbs of boost to get going but it stutters slightly and starts moving. I'm thinking about purchasing a Forge recirculated blow off valve for 1G but was wondering if it would help with my situation.

Thanks!
