N55 JB4 FeedBack HELP ME!!

Everything about the JB4 is so cool to me but I'm having an annoying problem , i have a strange Squealing sound coming from the engine bay when I'm coming to a stop or when i left off Throttle. It could be PCV related or ChargePipe related it's hard to describe, and i have no idea what side of the engine its coming from, when i come to a complete stop, the sound goes away, i really only hear when I'm coasting with my foot off the gas pedal. i hear the sound in maps 1,2 and 5, but when i set it to map 0, the sound goes away. Can anyone help me? PFA

Thats a nice car, anyways if you got the stock chargepipe maybe other things that can be must be related to boost since you said on map 0 its fine, it might sound like its coming from anywhere in the engine but try to find exactly what side and you will probably be able to tell which side it is because that would help a lot too! you saying you can only hear it while coasting might be that there is less sound from other parts letting you hear it so it might still be present when you are on the gas.

I'm full bolt on . My ChargePipe has poor fitment that's one of the Factors I'll check . But I'm sure it's PCV related. I'm hoping i don't have to replace any Seals
