Did you check that you had the RPM and tire size/diameter correct in the Engine/Drivetrain box in Bluecat? That can make a big difference.

Remember that Bluecat doesn't duplicate stock tables, it uses calculations to create new shift curves.

Whatever you do, don't go changing the maximum line pressure scalar unlike what you might run into reading how to tune your transmission on the internet. The PCM is coming up with a number between 0-96 and then using that to look up the force motor current in the force motor current tables. Since 96 is the highest column, you want to leave it at 96 to limit the calculation to 96.
Yes, misleading.
Pictured below is a compare of OBD1 $EE .bin files 3.42 vs. 3.23 The OBD1 compare is showing 4402 differences, not all the compare differences are transmission, and some of the compare differences are undefined. Tables shown have "Compare On".

Possibly using the 3.42 .bin file as the starter tune is a good plan?
