Yup that's slippage.

A *slightly* smaller belt and a new/stiffer tensioner will help

If he were to get a stiffer tensioner would there really be a need for a slightly smaller belt? I Unless by slightly you mean like an inch. Lol then both would be needed. But if you're only talking about half an inch or less, a better tensioner should be adequate enough to take care of the problem, right?

When was the last time you put a new belt on? I put a brand new one on when I got my Mechman, and I think rocking.that.eclipse had slip until he put a new belt on also. Gates Green belts are preffered I believe, and it sure looks like you have plenty of wrap on it.

Its not necessarily the tensioner unless its bad. I had issues on mine where the tensioner was not absorbing the bounce that your engine gets from it firing the pistons so the tensioner was bouncing around and causing the belt to get bumps from where it would be tight, loose, tight, etc during its cycle. I replaced the OEM tensioner with one from advance automotive and replaced to their belt and had mad belt slippage. I had replaced my idler pulley but that broke again from the bearing being bad a second time and the belt was still slipping and you could tell since the brand new idler pulley had the black paint worn off down to bare metal and the writing on the outer part of the belt was worn off. So I had dumped 3 belts from advance all of which I didnt have to pay for since they were all under warranty and got so sick of them doing the same shit after 3-4 months of use so I went to NAPA and bought a GATES belt for mine and it stopped all forms of slipping that I had. Before with advance auto's belt whenever I slammed the gas and it downshifted you would hear the belt squeal like hell and I had tons of rubber around my entire belt drive. I also caught on that my dad had the same issues and he ran the same shitty advance auto belts so I wanted to give gates a try and sure enough it fixed all my issues. Now I only have a quick squeal when I punch the gas and it downshifts but there is no wear or dust like that from the belt on my engine at all and my alt doesn't get hot like it used to from belt slippage causing the pulley to get hot.

Long story short, try getting a GATES belt and maybe a tensioner as well. Just get the ones for your OEM specs and see how it goes.

I have tried 3 different dayco belts and a new tensioner. I made sure the tensioner rides in the same location as the stock belt was before the smaller pulley I installed...maybe ill give the gates belt a try

What exactly is the point of this? Lol Are you asking for help or showing? ^_^

I wanted someone to confirm what I believed was belt slippage

How much load do you have on your alternator? Amps, fans, fuel pumps?

How much load do you have on your alternator? Amps, fans, fuel pumps?5 amps totalling around 6k r.m.s. One red-top under hood and 3 kinetik 1400's in back. I clamped the car itself with the radio off and it pulls around 20-30 amps depending on if the cooling fans are on.
