Torque management with jet dst I'm sure this has been asked enough before but I couldn't get the search to work for me. I have a 05 Silverado with the 5.3. I've been in the tune and played with the TM tables and some abuse mode tables. It's been awhile since I've messed with it but what I did do made no noticeable difference. Can't remember exactly what I did touch on without pulling it back up. Has anyone figured out a fairly straight forward way of turning the TM down with the Jet DST? Thanks.

I would suggest upping the trans line pressures and reducing the shift times too.
Try scaling the 1-2 pressures by 1.2, the 2-3 pressures by 1.35 and the 3-4 pressures by 1.1. After scaling any values that are over 90 change back to 90. Set the 1-2 shift times to .3 and zero the 2-3. The 3-4 shift times should already be 0.
