I would run two pumps, something big and nasty for the track and a smaller unit for the road, both in the tank if you can. Use your EFI to stage the pumps however you need them.

I run two 255LPH pumps and have the second one kick on at 3500rpm if the throttle is over %50. I am NA though and the second pump is mostly for redundancy but I am pretty close to maxing out one pump so I use it under those conditions.
