Broz - confirm I need a new fuel pump.
Went to the dyno today. A month ago, after having had the car off of jackstands for less than 24 hours and having done no tuning, it did 190 at the wheels and we had to lift at 6200 or so because it was getting lean.
I did some on-ramp tuning before heading back today, and thought I had the high rpm lean tuned it, but that's not the case. It still started to creep up to 12 at 6500, and I couldn't get that to come down. At that RPM I have about 10psi of manifold pressure.
So - this says to me that my stock fuel pump has reached flow/pressure capacity, and I need to upgrade it. The injectors are 550cc, I should have plenty of injector capacity left at only 200rwhp.
The DW300 is the one I want, correct? All the fuels I need, and not as noisy as the walbros? Will carry on with me into the future of built motors and EFR seks? Confirm for me this is the one I want: Deatschwerks DW300 Fuel Pump
Is there anything else I need to get to finish/finalize installation?

I don't have that information. I'm using an Xede on top of my stock ECU, I modify the MAF signal to the ecu to control fuel. Adding fuel from -2% to +2% in the 6000-7000 max load cells had only a slight effect on the AFR. A 4% swing elsewhere makes a huge difference.
Within the last couple of years.
How long since you last changed the fuel filter?
