granatelli coil packs for more HP?

Has anyone installed these coil packs on their supercharged mustang? What kinds of gains are we looking at?

Realistically, none.

Agreed. The only gains I see are if you're misfiring from blowing out the spark or something, and it's highly unlikely you're getting them for that reason. I'd suggest you spend the money elsewhere

I've been told by a couple of pros in the industry to stay away from aftermarket coil packs and stick with OEM coil packs.

I agree, I've got the MSD's and have found absolutely no benefit. Stock coil packs are plenty strong. There are 600-800 RWHP cars out there with stock coil packs. You just have to go 1-2 heat ranges colder and close the gap some.
