2016 Chevrolet Silverado 1500 whistling

I just bought a 2016 4.3L V6 Silverado. When I accelerate from a stopped position it makes a whistling noise kinda like a Diesel engine sounds. Only when you are giving it a goo about of gas will the nose happen, no other time will it make a sound. What could it be?

Could be a loose or torn intake hose. Isn’t this still under warranty? Let the dealer fix it.
