I recently made the move to Phase 1/2 w/ PB running the V2 intake. I've noticed in the upper RPM that the intake has a distinctive whistling sound to it. I'm assuming from the higher CFM being moved through the intake track and the air is getting split somewhere causing the sound. Now I don't care about the sound, but my girlfriend has taken issue with it. I've triple-checked my install (I'm a mechanic by trade so no dummy here) and it seems sound and by-the-book. I'm hoping to get some responses from other V2 owners to see if this is the norm or not. If it is, I'll have to see about getting the V4 maybe or just leave the girlfriend at home lol...

I have had the same issue with mine. I also have the same tune. It starts around 2000 RPM. No loss of power and once I get to 3500 rpm it seems to disappear. I have checked all hose connections, exhaust seals, vacuum lines....etc.
