I didn't read that you had changed the belt when you changed the idler pulley. That said, the current belt is either not under enough tension or it's got a build up of rubber in the pulley on the a/c. Basically, it sounds like it's just slipping during sudden load changes on it.
Get some "belt dressing" in a spray can from the auto parts store. Spray it between the pulley and the belt. If the squeal goes away the belt and pulley were probably polluted with rubber dust or something like that causing it to slip. If that doesn't work I'd go for a new belt before spending $60+ on a tensioner.
But, as usual, ymmv
good luck.

Try this. I was shown this by a mechanic friend of mine. It wasn't on the 'vette, but on my siverado, which is a similar set up.
Take a bottled water and while the car is running pour water over the serpentine belt. If the noise goes away while the water is running over the belt then all you should need to replace is the belt. The edges get worn and can cause this type of squeak.
If the noise persist than I would follow Matt's advice.
