KC's Fusion package swaps both turbos. The high pressure turbo comes up on boost fast and feeds the low pressure turbo, which compresses the air again for more boost and more horsepower.KC spent years testing and refining this setup before releasing it. It's for the guy who wants to really wake up a 6.4 and still keep the option of light towing. Pick the Stage 1 low pressure turbo for stock sized injectors, or the Stage 2 low pressure turbo if bigger injectors and twin pumps are in the plan.Core Charge: The price includes a $400 refundable core charge. Once you send your old high pressure turbo core back, the $400 is refunded.If you're running an exhaust brake, check fitment and clearance with your brand first. Some brakes can rub the turbine wheel or create heavy back pressure that's hard on the turbo and motor.
