So half a year ago, I got a Fidanza LTW flywheel with Sachs clutch when my stock clutch started slipping. At the same time, I had Eurosport underdrive pulleys installed. I've always had this strange grinding-ish noise on deceleration past ~3k rpm that I never had before, but that's another issue. I had read in another recent thread that having a LTW FW and aftermarket pulleys together was a bad combination? My flywheel no longer chatters like it used to, at all, which is something that I'd never heard of before. I was curious if something got tweaked because of the combination and my flywheel isn't 100% right?

Thanks guys.

The rule is no aftermarket crank pulley, since the stock one is a vibration dampener. I'm thinking something happened to the fluids in your transmission. Pulleys would have no effect on the gears chattering inside the transmission (which is where the sound comes from.)
