One thing I noticed in the tune, is the Fuel Overide is still set to 1. It should be the same as WOT Lambda.
Also, OP is not active in Mapped Points.
Change those, disable Shuffle switch and do another log and see if anything changes.
I'm not with my laptop right now so I can't look at it but check your maximum torque clip in the torque management settings. I maxed that out and my car did the same thing, just make it about 500 or so.
ok Fixed it. lt ended up not being the switch I had to remap the engine tq and tq inverse tables along with the DD tables. This is probably because the JLT is a much bigger housing that requires around 30% more fuel and effects the airflow and tq calculations. But after I remapped that everything is good and working
