Question Any real truth that the 2.5 RS runs lean on 1 cylinder?

Do the RS MY 2000+ not have the problem where #3 cylinder is always lean?

Is the distribution of fuel in the RS an urban legend or is there a uneven distribution of fuel? I have always found the idea than a 8mm OD tube going to each injector could have a lower pressure for 1 cylinder, a little out there.

There is a posted mod to change the fuel plumbing from serial to parallel (which honestly parallel distribution for anything drawn simultaneously would be superior to serial), but is it worth doing? Is there an issue?

I have a MY 1999 RS.
