replaced clutch now have engine vibration

[old power]

recently installed a ram hdx clutch assy with a fidanza flywheel,now the clutch feels great but i get a vibration from the engine at 2300rpm+, my engine tuner has had issues with fidanza before and suggests a ram flywheel to correct the vibration.

I too have had vibration issues with Fidanza (on Fords) in the past. I'd shy away from them myself nowadays.

thanks, i have spoke to several other people that also suggested to stay away from fidanza,seems the only way to repair is to balance the flywheel and pressure plate as an assembly.i've ordered a lightened steel flywheel, no more aluminum for me!!
