Hey guys, kinda new to this turbo stuff, but I recently added a knn intake and the intake has a nice sound when you let off the gas, but when your driving you can really hear the turbo spoolin is that normal or is it a possible leak? Thanks!

I think it's normal. It sounds like an air pressure leak when accelerating right? I have the same set up except I use a dry K&N-style filter (can't remember the name of it atm lol)

Adding a cold air intake will let you hear the turbo and bpv. You shouldn't have any leaks as long as you tightened all the hose connections.

Completely normal.
