[s-cars] fuel pressure

[Martin Baggenstos]

I have a quick question for those who are familiar with how to fuel system
works in a urS6. I am running MRC Rs2 software with the delphi #37 injectors
and I am thinking of replacing my fuel pump soon as it has 135,000 miles on
it and I don't know how much longer it will last. My question is if I go
with, for instance, a 044 fuel pump or another high flow fuel pump, will
this cause my AFR to become richer or should it remain the same as the fuel
pressure is still going to be limited by the stock 4 bar FPR. The reason I
ask is if I am going to replace the fuel pump, why don't I just get a higher
flow one in case, later down the road, I want to go for more mods and more
power, i already will have a fuel pump to handle it. I was not sure if the
software will be sensitive to changes with fuel pumps or all of this should
not matter since the FPR will prevent higher flow.
