[QUOTE="03cobra#2, post: 16527714, member: 52057"] So just thinking out loud. In a return fuel system with a mechanical regulator switching pumps for more or less flow should not require a retune. The lph of the pumps shouldn't matter. The regulator is mechanical and sets the fuel pressure....as long as the tune and install is correct. Always a good idea to have the frps hooked up in a return style anyway. You can log delta pressure and depending on how the tune is set up can compensate for fluctuations in fuel pressure. Let us know how it works out. [/QUOTE]
