I agree but the A1000 is a higher performance pump for racing purposes than what's found in OEM applications.
I do think Weldon is a better pump but back in the day the A1000 is what was recommended by the shop helping with my EFI installation and setup. I do have a Weldon pump in my supercharged C5 Z06 along with a Boost-A-Pump... again a modulated controller that increases the output of the pump as demand increases. The last thing you want while under boost is fuel starvation. As i understand the BAP uses pulse modulation to control the pump and boost pressure when needed.
