Zl1 Pulley/Cam/BAP questions for my first build

I realize a closed loop MAF setup should keep the AFR where it needs to be for part throttle, but what happens when you go WOT and get into the PE? If you are on the hairy edge of the pump at elevation, I assume you are out of pump at sea level?

Just a genuine question. I wonder if folks in some areas of California need to worry about this (i.e., if you build and tune it at 5000ft, then take a trip to sea level for a drag strip run, I'd imagine you need to overbuild your fuel system to account for this). Never really considered this myself, because I'm only at about 1000 ft.

To be honest i am not sure, I would be curios to know this too. I asked JDP about my pump shortly after i bought the car because i have read about how the stock pump cant handle much more than stock power levels without a BAP. they told me that the pump would be fine at that power level and i shouldn't have to worry, he said it all looked fine when tuned the car too. So i never looked any more into it. but i would also be curios to know if lower elevation would be to much for the pump to handle.

now i have more questions HA
