I emailed Wavetrac tech and they said it could be the "preload of the driveshaft", he said if the driveshaft center bearing is not correctly loaded (I'm still not quite sure) it will have the symptoms even you put the original diff back, now I remember my car was perfect before the first pumpkin swap.

NOISE:
I notice a new noise on my 335i, same noise my old E46 made after the Diff installed. It's like, on flat ground, no ebrake, put in first gear, and let go half of the clutch till in JUST engage, something goes make a loose sound. Push in the clutch, sound is gone, let go half way again, li li li li li noise (don't know how to describe lol)

I will have a video of the noise up soon! I suspect it's what Wavetrac told me, the driveshaft!
