I have recently installed a Sonnax transmission line booster in addition to the performance TCM tune on my Jeep GC 5.7 and just want a heads up that the tune and device are not known to conflict. Many thanks

I did have a problem with it actually, I ran the sonnax great then bought the tuner, had it installed and the sonnax started holding 2nd gear and wouldn't let me shift, but then when I unplugged it the truck ran perfectly fine with the tuner....

If you are asking me, I would not know why that happened...

I have been running the Sonnax along with Predator 93 custom tune for over a year, no issues except better shifting
You do have to reset computer once in a while because of TCM adaptive learning. (You can only fool the computer with the resistor Sonnax harness for so long..)
