Iron block 408, 9.5:1 comp, ls3 heads with a lot of work. Gt91 turbo, 91 comp wheel, 94 turbine. T6 flange. Brute speed blower cam, 23x duration 114, 600 ish lift. 102 nw tb and gm pp spidered intake. I am either going to add a 255 pump so that's three, or what are the other options! Twin 450's? Or ????
Sounds like you could be making enough power that your pumps are running out of steam to me. Doesn’t really matter how you add more pump. Whatever is easiest for you. I like the idea of less pumps personally. if your current pumps are intank, I’d replace them both with the 450lph e85 walbro pumps.
If your external and running inline pumps, adding another 255 would be easiest. You can use the 3:1 shop air fittings for a nice cheap 255 inline coupler. I just tapped out the 3/8” hole on the bottom to -10 fittings thread pitch and go. The one I did turned out slick.
2 of these. 3 pumps in the middle with cheapie push lock AN6 fittings.

I am running dual in tank 255's with that little shower head thing with two of the ports used. I think I might ditch the 255's and do 2 450's. Do you know of they fit in the stock 4 the gen bucket?
I am going to run it on the current setup and see what my dc is for now. If my injectors keep trying too add fuel and pressure and afr isn't where I want then pump change will be in order.

80# hiZ injectors are under $400 shipped and will make 850+ to the wheels on E85 using the OEM LS1 or Truck fuel rail. Thats at 69 BAse and 24psi. At this point they are pretty much maxed out.
Do a search, this has been talked to death 100+ times.
If you are maxing out 80#injectos before this you don't have enough pump or you have other issues.

69 base!!!! damn can the ecu control them without mechanical lockup at that psi?

Most of the injectors I've read about are rated to 100psi. Keep it under there and you *should* be good. I'm not makin any promises though!
