This is on a P600B W/ 12 Lb 12rib setup.

I have what almost sounds like a slight rod knock at idle, but it's something in the SC system. If I remove the belt the sound stops. All the bolts are tight; pulley is tight, no excessive play in the tensioner or head unit.

Anyone ever experience this? Could I have the tension too tight?

I had a similar problem with my Vortech V2 S-Trim a few weeks ago.
The SC ran great for two years and suddenly started making lots of noise.
I sent it to Vortech and they did a major rebuild. They told me the gears went out in the SC. They had it for about a week.
Fortunately, they honored the 3yr warranty and nulled out the $1089.00 cost of the rebuild. I got it back yesterday(they even paid the freight) and reinstalled it. Runs better than ever now.
Vortech's quick warranty repair was impressive.
I don't know what ATI will charge for a rebuild but it probably won't be cheap.
Good Luck.

Thank you for the reply. I hope your wrong. I've got no funds right now and would rather replace it with a bigger unit then fix that thing.

It has less then 1,000 miles on it since ATI checked it out when I bought it, and I shift at 6200.

It would not be a good thing if I hurt it!

check out the tensioner.. pull the belt off and see how the head unit itself feels when turning it by hand. Have you had that thing dynoed? im running pretty much the same set up and was curious as too what others with it are putting down
