BTW, on my previous 540-6 which came with 2.82 diff, when I changed it to the 3.15, the car felt MUCH faster but I lost 1 mpg in the process mostly due to the fun factor increasing.
When I put the old 2.82 diff back when I sold the car, the car actually felt sluggish!
Just out of curiousity,what did you do with the old 3:15 diff? If you still have it,i may be interested in it if you are looking at getting rid of it.
