unfortunately as Mellon found out recently a walbro is at it's limits with a 35r
he had to add a kenne bell boost a pump in order to maintain enough voltage to feed the beast
in my opinion a 35r is where you drawn the line to needing a double pumper or something off the likes

on my stealth I have a fuel pressure transducer and can log fuel pressure vs boost to make sure it's rising 1:1 from 25-35psi it's very handy for finding fuel pressure issues. Do you have anything like that with your setup by chance?

with pump gas I'm at 11.5:1 AFR maybe you're in the 12.5:1 area saving some fuel and running some massive injectors. Are you in any meth/alky which would lessen the need for gasoline? just trying to understand your scenario because that's pretty interesting.

Sorry thats on race gas (c-16) Shouldn't be that big of a difference though. Have you taken off your fuel rail yet? Just wondering If you have seen the size of the inlet in it?

The walbro 255HP will start to have flow issues around 500-540 whp.
No one NEEDS a regulator if your not running dual pumps at the same time. regulator is still nice to have but isnt needed.
