This is driving me nuts!
My 06 GT is driving me nuts lately. I have recently replaced the belt tensioner and belt and I still get a squealing noise. First I replaced the belt but the squealing came back after a couple of weeks so I replaced the tensioner. That fixed it for a couple of months until now when the squealing has returned. I removed the belt and spun every pulley by hand and no noise from any of them except for a SLIGHT noise when I spin the alternator pulley. Any help/advice is greatly appreciated, I am out of ideas. Thanks in advance!

Pick up some belt dressing, solely for trouble shooting. Spray the channel in each pulley one-by-one until you find the culprit. My guess is you have a pulley out of alignment and it glazes the belt(s) after a short time.

I did notice some dried up belt residue on the smooth idler pullies. Is that from the belt getting glazed? I sanded and cleaned those idlers yesterday and it didn't change anything sadly.

This is what I was considering doing, I just hate to waste money on another belt without finding the cause of my issues. I do know the Gatorback belt is supposed the work well for slight pulley misalignment. If I can't find the problem I will give the Gatorback a try.

You are right man, I need to identify why I am glazing a new belt after 2K miles. What is really weird is the noises are different with the 2 belts I have but both have squealing for sure.

Any change in belt materials or construction, even the tension, can change the pitch. I believe you're on the right track to finding and resolving the problem.
Too many people do what I refer to as "selective-modular-replacement" where they simply keep throwing parts at the problem until it's resolved. I suppose that's fine if you have the means to afford it.

I went out and decided to do a test with the water bottle. I sprayed the squealing belt with water around the tensioner area and the noise went away. From researching that means I have a pulley out of alignment in that area. I went ahead and removed the belt but nothing looks out of alignment.

I know that it's difficult to locate and to be honest, I've never detected the mis-alignment myself; I've only explained my findings and assumptions to a shop and they replaced a pulley on another vehicle of mine which solved the problem. When they pulled it off, they laid it on a flat surface and you could see daylight under about 25% of the circumference.
