From my experiences with the LS1 underdrive pulley you should see a 10-12 HP increase, when you put add an overdrive alt pulley you should generally sacrafice about 2 hp.

Like said above, 10-12hp is normal from underdrive crank pulley. The only reason you'd need an alternator overdrive pulley is if you have charging issues after the crank pulley install. Being an m6 car, I don't see you having a problem since the manual cars idle faster than an auto. I just have the crank pulley and I don't have any charging issues idling in gear @ 700rpm.
The pulley is a good mod, and they do not cost $300, even with belts. People most usually wait to put a cam in to do it though, since it has to come off anyway. The overdrive alternator pulley is only needed if you have some damn Baja headlights on your camaro, or a huge stereo with another amp or something. 99% of people get by with just the pulley.
Nods, the car is being worked on by Jeff @ CAM, and he called to let me know the alt pulley was missing
Thus I was wondering what would happen
If anything
Thanks for the input
Yea I do have a pretty big aftermarket stereo on the car. I guess I'll have to drive it around for a week to see what happens
