With the stock fuel system, the key will be limiting boost on the hit. When you look at the logs you'll always see the dip in fuel pressure when boost spikes then after that it catches back up and actual air fuel is pretty solid matching commanded.
The goal with aftermarket turbos would be to carry the power more in the higher rpms when the stock turbo is past it's efficiency point. You should be able to match the peak torque or do slightly better and then improve peak horsepower past 5k.
I believe Walsh is including an upgraded lift pump which should minimize the fuel pressure dip as well.
We haven't tuned one yet on our dyno but I'm currently working with a shop that has a truck with "modified" stock turbos. No numbers to give out yet, but the log looks pretty good and seems to handle timing better with this setup.
