Raise your rev limiter to compensate for your flywheel. Since it isnt damperd you must pump the clutch peddle and give it more gas then normal to get moving. A heavy stock flywheel remains spinning when you are stopped. Lightweight flywheels tend to chacter and be difficult to get moving when at a dead stop because they stop spining.

Thats not what im talking about.

Example. Im at a stop sign, I just start to go but someone cuts out in front of me, so i hit the brake and push in the clutch. Revs drop to quick. And can some times stall. Even from a blip of the throttle just sitting there, it will sometimes stall.

If that is your concern, go back to a dual mass flywheel. Seems to defeat the purpose of a single mass one if you want to slow the rising and falling of the revs....Just my opinion of course...

the benefits/purpose of a lightweight flywheel is to transfer power more efficiently. The faster your revs go up and down, the faster you can manipulate power output.

If you would like to sell your flywheel locally(near philly) I am interested

Josh-

It sounds as though there has been too much shaved from the flywheel. Many race cars don't idle at all since the flywheels have been shaved to save as much weight as possible.

I know exaxtly what you are talking about. It can be scary pulling up to a stop light not knowing if the car is still going to be running when you get there...

My suggestion would be either to go with a flywheel that is slightly heavier, or get your software tuner to give you some idles support.

There is a fine line with lightweight flywheels.
