So I'm not crazy his 06 4.8is valvetronic is not the same punch at low rpm's as my 01 4.4i. The biggest difference is his suspension rides much softer than mine. I can feel every hole or bump in the road. My wife likes her X3 ride over my X5.

From what I can tell, the valvetronic has robbed the torque from the
car. There may be associated tranny involvement with the 6 speed that makes us feel less torque also. Don't get me wrong, the car is "fast",
I just think most of us would like to feel it more than we see it...imho.
