I'm having similar issues as you but with a different brand lighter flywheel. I'm using Competition stage 3 clutch with 7lb lighter flywheel from stock. I'm car stalls if I'm in neutral and I give it some revs. The rpm drops too fast for the fuel map to catch up and induce rev hang to prevent it from dipping to 500rpm and dieing. I have a Greddy turbo in the car for more than 2 months and never had this issue till I got the clutch installed 2 weeks ago. See video for how it stalls. I think I need my tuner to adjust the tune for the quick drops in rpm under no load conditions like free reving the motor or reversing into a spot where you slip the clutch and let it rev hang sometimes.
