What did Eurocharged tell you when you were ordering your tune?
I expect that there is some room built in to the stock pump, but it's probably a car-by-car thing that will need to be logged to make sure your LPFP is keeping the pressure to the HPFP high enough. At least that's how it was on my 335i (some cars could run a higher ethanol blend than others before needing to upgrade the LPFP).
