I would try changing the part throttle and full throttle rpms and speeds for all modes to the numbers you have for D. It's possible that D is not tow/haul, that's B on the 6 speeds. To be sure make a tune with all modes with the high rpms and mphs that cannot be reached for the 4-5 upshift, and it should work.

It looks correct, other than the chance that the tables are not correctly labelled, which is why I'd try the above to make sure. If that fixes it I'd then start putting one table at a time back to stock until you figure out which is really tow/haul. If this first try fixes it I vote for B to be tow/haul, not D.
