Default Anyone ever maxed out an A1000?

My car has been running flat up on top and Ive been doing a lot of troubleshooting. The car has a full fuel system, fuel cell -10 lines, split at the rails, 95# injectors. I logged a couple of runs with HP tuners, and it looks like the fuel pressure is dropping. I have the pressure set to a base of 43.5 with a 1:1 Ratio for boost reference. So simple math tells me a 22# boost, I should be at 65 psi. So either the regulator is failing, or Im just running out of pump. Anyone had the A1000 be too small for them? Attached is my HP tuners Scan config and a log from last night. Thank you for any input.

Edit, I can't upload the config, but the fuel pressure is the standard PID in the scanner, or I can Email it to somebody.

How much HP are you making or better yet your BSFC? How old is the pump and what filters are you using and where are the located?
