Help with center diff in Jammin conversion

[nl12]

I need help getting my center diff tuned in my crt conversion 8s, 2240 power, I started out with 10K and it unloads on the front end on anything over 3/8 throttle, so I switch to 50K in the diff, it helped the unloading a little I can do maybe half throttle but the diff gets quite hot, it may have even boiled the fluid. I would like to be able to use more of my systems power without the front end spinning like crazy, I can go to a 100k or higher diff oil but is that really nessisary? I am afraid the diff will just heat up even more. I will duct tape the inside of the tires to minimize the tire balooning maybe that will help some because now after the front breaks traction the front tires balloon like crazy and I have to let off to regain control. I would'nt mind being able to do wheeles too. Should I switch to the highest diff fluid I can find in the center or will that spell trouble to the rest of my drivetrain?
