With stock turbo, fueling isn't really the bottleneck until you use ethanol.
400whp requires 350lb*ft@6000rpm. That's all about how octane holds up boost and IAT.
Realistically, 50-60whp is about as much as you can expect to gain from flash tune without using meth and ethanol. To hit 400whp really depends on the baseline number you use.
