Man! I got worried looking for the LE vendor forum there for a minute, good thing I clicked this one and seen your post!
Keep rocking out man! Great to know you'll still rep LE!
Glad nobody was hurt!
I know I can push through my brakes pretty easily at the drag strip in 4x4, and i'd think any tuned 6.4 could as well. Especially in a panic situation where you may not of had the brake fully depressed. Bone stock could probably do it as well, but not sure.
Your right foot will have more to do with it being "safe" than the actual tune choice.
Do you have a monitor? If so, then its fine to run and just keep an eye on things.
Well they do different things so you have to decide what you're trying to accomplish.
You dont need them, just get proper tunes, monitor EBP and if its too high have the tune reworked.
I have a few buckets of gear oil too, just waiting on front locker install and new rear Dana 80 to arrive before I do it though.
Only put a few miles on it, but seems smoother so far!
