I thought I remember reading that Diablo Sport tuner can change the shift pattern,

I don't think the Diabolo Sport Tuner can do that on an 03....someone will chime in.
But I DO KNOW that the Torque Management free mod can and does work on our trucks. Do a search on this 5 minutes to complete mod to wake up your WOT shifts.
However......we still have to live with the double od and the poor shift schedule that Dodge lumbered us with ha ha ha.

As stated, between the sloshy transmission and horrible shift schedule PLUS, it sounds like you have 3:55 gears to boot which hasn't been mentioned.
Any other year besides the '03 ans Superchips allows full custom shift scheduling. Partial throttle up&downshifts. YOU decide at what throttle % you want the truck to shift and react to. But since you have an '03, the TM mod is all you can do.
The TM mod will only make your truck shift faster/harder. It will not help you with the problem you have posted about. Dodge cuts the ***** off on the shift. Up to 80% power reduction while shifting.

Your only recourse here is to:
a. trade in on an '05
b. send your TCM to B&G & hope for the best
c. convert to an '05 PCM setup

Welcome to the site. I think an 04+ PCM will work for him though too

How hard is to do a 04 or 05 PCM convert?
