I suppose some of the V6s vibrated, but not mine (2006 convertible
automatic), and with the BamaChips tune it was not top-speed limited
at 113. It was stlll accelerating at 130 (5300 in 4th) when I
chickened out.

As for the drift: even before shocks, springs, and sways were
upgraded, no drift. The Classic front chin spoiler and lack of rear
spoiler other than a "lip" may have had something to do with that.
