Strong vibration/Stutter under heavy Acceleration?

[Grangalan]

I've had this weird vibration under heavy acceleration for a while now. Especially now that i am Full stage 3. Basically anytime the car sees full throttle acceleration it feels like the rear end is stuttering, almost like bad wheel hop. It's very audible as well. I havent had time to look at it since i've been slammed with work but i figured i'd get some foresight.

could be the prop shaft:

Different than the loss of power you get with a vaccum leak?

This is a bad inner or outer cv boot. You cv joint has probably gone bad. I have the same problem and that was the solution. Just my .02

stock rear differential mounting can be equated to a bunch of rubber bands, so it may be an issue, your clutch could possibly be slipping too.

I was thinking possible diff mount as well. Other than that i can only thing of U joint or the CV's. The stuttering comes from the rear only , and from the feel rear right. The clutch is ruled out since its a brand new properly broken in stage V southbend.

Had the same issue with my front joints, after a new/rebulit went in it was gone, that is my story
