do you think this would free up some power on a stock 94 GTS? Does anyone have this flywheel?

Nope, I've seen it first hand. It all goes back to the definitions of power and torque. A dyno actually measures torque. Torque is how much work an engine can do (for instance it can create 300lb of force at a radius of 1ft for the center of rotation = 300lb-ft, notice its not time dependent). Power is calculated from torque in the dyno software. Power is the speed at which the engine is able to do the work. RPM now enters into the equation. Since the rotating parts are lighter, the engine revs faster. Its not making any more power within the engine, but the lighter parts 'freed' up some of that power and thats what the dyno sees.
