High speed squeal

Hi guys..

I have a question for 2012 owners and 2nd gens in general..

Has any one noticed a squeal or howl at high speed?? Recently on holidays I had to do a couple of high speed passes to get by traffic there is a noise that almost sounds like a warning alarm at about 150-160 KPH..

My truck is going in to the dealer tomorrow for the supercharger install and I am wondering if indeed there is some kind of alarm at high speed or if it is something they should check out.

Thank You

Blygy

 

Sounds like the windshield may be leaking air past the seal.
