You are most probably correct xwedge. I know my 07 CX7 was factory tuned to deliever torque at 2500 rpm and the same engine in the speed3 had the torque peak at 3500, I believe.
hmmm, wonder what a larger engine option will do to the resale value of ours....
+1. I'm not sure it would have any effect on the value of the 2.0.
