The dyno graph clearly shows no issues with the A/F when tuned. I sent you the graph or we can post it.
stock pumps go all day long past past 400 rwhp and many people spray cars on stock pumps and make near 500 rwhp
is a 255 pump recommend @ 500 or more HP? sure it is and highly recommended, but the point being it has done the job many times over

it really depends on whether it is forced induction or naturally aspirated when the damn pump is going to run out.
i don't understand why people still ponder this question.
Naturally aspirated I don't know when the stockers die
Forced Induction.... its honestly pointless to ask, as if you go this route you indefinitely need injectors.
500RWHP Naturally ASPIRATED you will need minimum 37# injectors. I recommend 42# or higher.
My friend is making 474RWHP naturally aspirated and uses 37# I believe, but I also think he is at a 7x% Duty Cycle
Get with Lonnie, he is great. I recommend getting from him the Racetronix kit for sure and 42# injectors. 500RWHP Naturally aspirated you should have room to grow

^^ not 500, fic has 42lb injectors for like 240 bucks, they are a sponsor and are guaranteed for 3 years, also racetronix 255 is the only way to go imo, i have both of these and its handling my set up quite well...
p.s. racetronix fits in your fuel tank just like stock, which is a big deal once you dig in there...

28.8# injectors are good for maybe 400-420 rwhp from what we see ( safely )
I will agree Racetronix appears to offer some very nice bolt-in setups for fuel delivery.

So if your running something that is laying down 550whp 42# min but if I want to run some juice (175-200 shot) then what would you suggest? I dont want to run out of injector while on the bottle but I also dont want to wash my cylinders when off the spray.
