stage 1 chatter

[Goldcuffs]

Hey guys, I just installed a spec stage 1 and I have quite a bit of chatter. I put in a new ford flywheel, t/o bearing, pilot ect... I even tore it all apart and cleaned everything just to make sure there were no oils on anything. Spec said it was normal for a stage 1 and that I should have went with a stage 2. I have a 2.73 rear gear which I know will make chatter feel worse. Has anyone else experienced this and what was the fix?

Someone had a thread on here with the same problem but I can't find it. Does anyone remember seeing it?

I did the spec stage 1 and fidanza aluminum flywheel and I had somewhat bad chatter at first but after a couple weeks it went away. I also have 3.73s to help it and after the alum. driveshaft it seemed to help even more.
