I usually end up at about 75% for max effort cummins tunes. That's typically only above 3000rpm that I give it that much timing and on big injector trucks. On stock injector trucks I typically stop at 60%. I've gone up into the mid 80%'s before on a truck. One thing you really need to consider is end of injection. If you keep the injection even going too far past top dead center you will end up with a melted piston.
