    6.0 Powerstroke Transmission Defueling During Shifts 5R110

    I have a 2004 Ford Excursion with a 6.0 Powerstroke. Big fuel and big air, I have a tune that is making good power but I cannot keep the truck from pulling fuel during shifts. I feel like I have all the torque limiters turned off and have pressures turned up but for some reason the truck just slowly pulls a ton of power, makes the shift, and then gives the power back. Attached is my tune, a data log, and the screen I use to log. I also have a video of the dash that really shows how bad it is. Any help is appreciated.

    Try this Excursion_Low_Idle_10_22_23_Trans JwRev1.hpt Also put some more timing on the big end and watch it sing!
