Sharp vibration at 45mph

Sharp vibration at 45mph
So I'm getting a sharp side to side vibration at 40-60mph (all rpm range). I've had my tires balanced/rotated 3 times and it hasn't changed anything. I know there is a TSB for a vibration at 50mph at 1500rpm but trust me, it isn't that...this is at all rpm ranges and the higher the rpms the sharper the vibration is.
I'm thinking it could be engine mounts, but my car idles fine and there isn't any clunk noises. Now my car was on the dyno recently and on WOT, the engine just shakes (kinda scary!). My tech was thinking it might be the CV joints, but hasn't heard of anyone having to replace those.
Any ideas??

Tell the dealer to nuetralize the motor mounts as one of them may be binding. If you have an AT, doe sit make harsh shifts or a unusually loud clunk when changing gears?, the the motor mounts are binding. Also I would have them check for any bad suspension components.
