Default fuel type/injector questions

make me some recomendations...id like to run e85 but i dont think i have enough injector

6.0 with a S480 (1200fwhp)

i currently have tripple gs340s walbros in the tank with -10 feed and -8 return

i dont mind running like an 80 psi base but that still will be short at 100 psi correct?

what other high impedence injectors are there for stock pcm?

You never stated your injector size.....

One thing for sure is you will never run 80psi base or boost reference from there with a Walbro pump. You should operate a Walbro pump under 65psi max pressure so you get the optimum flow.

Forget high impedence, you will need a large injector like 120#, plus a lowered base pressure (43psi)to allow boost referencing.

You should be asking them then, because my recommendation stands.

You are misapplying the pump for the application & will cause it to fail prematurely.... plus it will not flow well at 80psi. If you want that extreme pressure, you should be looking at a different pump.
