I have not switched my fuel pump yet and don't seem to have any issues, but agree that it is not a bad idea. I have yet to talk to Joshua about this, but upgrading the fuel pump has never been brought up in numerous discussions. From what I read in a similar post today, the supply wires should be replaced/upgraded as well, if you change the pump. I did swap the fuel pump in my FL car to the Bosch 44, per reccomendation from LR. Which backs up the rumor that it is required in this application as well.

I am running 18 psi and would guess around 375, but no dyno yet, waiting on WB install first. I have 295/30 18's on the rear and can boil them at will in second at any speed. Third gear is a handful as well on the street. This car is a blast now!
