Larger fuel pump

[euro_urs4]

is it necessary to change out the fuel pump on the aan motor if going bigger turbo? or will the stock fuel pump flow enough fuel to the motor

depends on setup, what BHP you want to run?

for me the pump or my aby pump started to drop away after 300 or so. reason i can tell that is injector duty and amount of trimming needed to get it back to where it was.

afr's went from rising towards 13 to dropping towards 8.
