Car shutters when leaving from a full stop??

[Coupe50h]

I just replaced my clutch without resurfacing the flywheel, i can totally understand the wear pattern thing, but my pilot bearing was fine also, with a swap back to my original clutch cable, im getting real smooth clutch engagement, if i ride the clutch out from a stop i notice it shudder just a tiny bit, nothing major, i went to the track wednsday dropping the clutch at 4k and smelling clutch on the top end, im breaking it in right now it's brand new, and grabbing real good, almost too good, i come close to killing the motor at times leaving lights lol, hope you get it figured out.
