I be a Tweecer tuner.:icon_twisted:

My boosted 4.0 makes more power and I am taking better advantage of it with my 5R55E tranny tune.

This is what I did:
Performance
It shifts quicker and firmer from 1st to 2nd and 2nd to 3rd during hard acceleration.
Shifts at higher speed/RPM during hard acceleration (red-line @ WOT).
It downshifts at higher speed/RPM to initiate hard acceleration.

Economy
It shifts into 4th and 5th at lower MPH/RPM at less than 1/3 throttle. The Torque Converter (TC) has been made to lock earlier in 4th and 5th gears.

:dunno: Thought there might be interest, I can help with questions????:icon_thumby:
 
Sample, my 2-1 downshift schedule. The top line is new tune, the bottom line is stock. MPH on Left and Throttle position across the bottom:

Cool. Maybe one day I'll have the place to work on stuff like yours.
