easiest thing you can do is go to a Manual lock up switch...
then its 100% decided by you no matter what..
its just a pressure switch and a 12v source...
so it should be fairly simple to modify it to use a manual switch to force it into lockup when you want....

Normal lockup is around 38 - 40 mph. Why is yours at 50 and why would you want it higher ? Anyways, the lock-up speed is changed via a tune.
