***problem fixed * ***Need help identifying a noise

I have a 2016 Z06 with 11,000 miles on it. When I'm cruising around 65-68 mph down the highway I hear a noise that sounds like
it's coming from the engine area. At first I thought it was a spark knock but realized that under a pull it disappeared. It doesn't matter
what mode the car is in and if the cruise control is in use. When I hear it if I lightly touch the accelerator the sound goes away. If I
continue to cruise the sound comes and goes and no particular pattern. This is the first supercharged engine I have owned and didn't
know if this was associated with it.
Thanks for your help.

************ The supercharger idler pulley and belt was the issue....they located a bulletin stating that this noise could be repaired
by changing both. Put several miles on the car this weekend without hearing anything....easy fix *******
