On the right had side of this page you will see "Duty Bias". He wants you to add 20 to each number. So if it says 10, 10, 15, 20, 30...
you would change them to read 30, 30, 35, 40, 50...

After you're done click save at the bottom and log some runs and send them back to him.

It's also very hard to tell what your car is doing from 0-60 runs. It's much better to do 4th gear pulls or 60-130 runs as there is much less variables to consider.
OP read the posts in your own damn thread. It seems you have no idea what you're doing and you're gonna blow your motor or trans, or diff trying to launch the car 20 times a day, every day. Take your car into a shop familiar with the JB4 and let them fix your car, Hockey explained how to change the duty cycles and you just set them all to 20, jesus fucking christ.
