Good to know. Right now my 13 yr old GS400 with 203,000mile would beat my S in a drag race by a large margin.
What you say about the the richness make sense as I get a rather significant uptick in performance on cool nights. I realize that engines always run better in cool weather, but going from an
OAT of 80 df to 65df should not make that big of a difference, but in the case of my car, it makes very a noticeable difference...
