And if I switched back to the stock flywheel would that fix my problem?

It's totally normal, and won't harm anything. Everyone that has switched from the oem dual-mass flywheel to a solid (one-piece) aftermarket flywheel has had this noise. It's usually worse with the a/c on. It comes from the hearing gears in the transmission 'slapping' against each other whenever the rpm in the engine changes (which is very frequently). An oem dual-mass flywheel eliminates this noise by absorbing the rpm changes - the dual-mass flywheel is two independently-rotating pieces connected with springs, so rpm changes are absorbed by the flywheel. The heavier oem flywheel also makes the car easier to drive, at the expense of rpm responsiveness...
