I know that warming fuel in the tank has a negative affect on fuel mileage. This is the whole reason of new cars going with the returnless system.
Most Tuners go overkill as a method of extra piece of mind and give room for futher performance gains later.

I will be replacing my pump because the shrader valve at the outlet of the pump that maintains fuel pressure when the car turns off is intermittantly not working giving me a long crank time. I think I may stay with the 255lph as I will be trying for that 300whp goal. Blown XA is pulling it off without a sleeved motor and has been reliable so far. I will try the same.
