I dont think theres anything wrong with the car
im assuming the ect was not in power mode
and since it sounds like your a generally relaxed driver the ect has learned your style
if you want it to be able to rev fully, reprogram your ect

From dead start floor it and keep it floored until it runs throught all three gears, and do this about the 6 times , it can be done in a few days and you should notice that the RPM's should start to raise on shifts.........after awhile the trans will shift well into the red line ( only when in ETC mode ) but in regular mode the car will shift much better than before.
