Loosing 37lbs from flywheel swap. Gains?

I have a opportunity to swap the 50 pound dual mass flywheel in my CTS-V with a 13 pound aluminum. Normally the flywheel in this engine would weigh something around 24 pounds but GM went with a heavy dual mass to make driving easier for the old guys who they expected to buy the car. Seems like a substantial deduction from the engine. I'm wondering if anyone would like to throw any mpg change guess out.
