After having some more time in the seat I have a few more observations about the update:
- Both the shift points and kickdown seem to have changed quite a bit. Before it seemed it would almost downshift 2 gears and surge forward when trying to get out of the "dead zone" - now it's much more predictable and the dead zone is gone.
- Less throttle input is required to get up to speed. Driving around town requires less effort as the engine seems more dialed into the sweet spot in the rpm range. I believe this is the main reason there is considerably less DBW feel. It's essentially like a free "sprintbooster" direct from Chrysler.
- Without a doubt the engine seems to run a few hundred rpm higher at low speed like the TSB notes.
I cannot wait to see what aftermarket tuners can do with the Pentastar engine if this kind of gain was to be had at conservative factory specs. I have a feeling there are substantial gains to be had simply by further tweaking the tuning and shift points.
