Unfortunately, it is sort of the nature of the beast. 6.0l's just do not come of idle very well, especially if you floor the throttle. It has to do with the way the VVT and PCM operate together. When you floor the 6.0l from idle the PCM demands more boost and limits the amount of fuel injected until that boost occurs, in the mean time the VVT vanes deflect hard to build the boost faster. When this happens there is an initial rapid build-up of back pressure until the turbo spools. Once the pressure is sufficient, the vanes open, pressure is released, fueling is restored, and tires break loose. Some tunes and modules will give you more initial fueling to help, but the best remedy is to roll the throttle or power brake.
