Alright this is interesting. let discuss 3 areas: off idle from stop, manual shifts, freeway passing.
Off idle from stop:
Off idle take off; the car could and has at times had this hesitation thing, but its not the engine misfiring or running poorly its delay from input at the throttle to actual moving the vehicle. This has improved to point of not being detectable ever. Another thing associated with this is, taking off, having to let off the gas, and then reapply the gas it would do abit of shock thing to the drive train. This is gone and its fluent like an automatic should be.
Manual shifts: I do this in long descents so I don't ride the brakes forever and there is no change there. However, on the gas at or near WOT you previously had to shift at 3K because if you waited till 5k it would redline and go into fuel cut. IT NO LONGER DOES THAT! I can now shift at about 5.5 to 6K and it hammers 2nd w/out fuel cut or being buried into REDLINE! A very noticeable and BIG Change! This helped the other gear too but its not as obvious.
Freeway passing: Previously it didn't have enough feeling regarding engine response to push on the pedal and KNOW what get it would drop into. For example a 55mph you to slowly push on the gas and either get a gear drop of 1 or 4 (as in 2nd gear). Now I can push use the throttle to select a gear. Its no longer ALL OR NOTHING!
I'm surprised that such a simple thing affects the driveablity so much. If you have any of these issues - try the slow down, slow up throttle action. It seems to help the overall response of the throttle.
