Now that I think about it, Mbpsychoss is the one that originally told me about the Gator Backs on a different forum. They work great!

 

Dealership will just note that it is normal and or like other identical vehicles tested.
My 05' VHO does the same thing. I think the tensioner is at fault personally.
The GDY belts may not make the squealing noise, but I bet it is still slipping slightly. Different rubber compound I'm sure.

My '05 SS did the same thing when it was stock. I put a magnacharger on it and the squeel went away.
