I'm on a lot of forums, this is the only one with this level of bickering.
And the ratio of bickering:useful or accurate advice is bad. Real bad.
I'd be checking:
1) Wheel Speed Sensors
2) Brake Proportion Valving
3) Unusual wear on brake pads on offending wheel vs. other front wheel.
I'd be less inclined, in fact would never, spend any time hunting for a programming solution to any such stability system. WHAT it is doing is likely called for. The EFFECT of what is doing is not good, lies with the execution which might lie with the above systems.
OP sounds like he's got enough experience to know not to run 4HI through any major on pavement turns, regardless of speed. Once you learn for a FACT that is not ok to do, it sticks with you long after the prop shaft and tcase are repaired.
