If I wanted to max out my injectors I would realistically need to upgrade to Walbro 400
Taking max duty % and raised pressure into account, four ID1000s will flow 240-250 lph.
So at 60psi fuel pressure and 30psi boost pressure - you need a pump that can do 250lph @ 90psi.
DW300 does 250/230/205 lph at 70/80/90psi
Walbro 400 E85 does 335/328/268 lph at 70/80/90psi

we already talked about it in this thread. walbro 400 E85 (part #F90000267) is the best pump evarrr

if everyone did what Fae does we'd all have cars that didn't run and when they did, not well. And we'd all tell everyone else to do the same thing because it's the best setup.

What? You only rev to 8,000 rpm?!
Anyway, all I was saying was that it's... non-linear. But you could fix that in software and get the last couple percent. Wow, just not much of an improvement, less to gain when 95 is what you get (yay sequential).
How much fuel are you using now, then, as in a percentage of the capability of the injectors?

Yesterday went to the E85 station to fill up and met an SRT-4 guy there. It was the first time I saw someone else using the E85 pump. Long story short we went on a date did a short race. From a roll in 2nd, once I got to 4th, I was clearly walking away.
He said he has a Precision 5758 @ 29psi and that dyno'ed at 450whp and like 490wtq or something stupid like that.
Yeah, I beat a Neon. I'm special.

Tell that to Lexus
Take the roar from the racetrack to the on-ramp. Born on the grueling Fuji International Speedway, the 2013 IS F is the fastest, most dominant sedan Lexus has ever built. A 5.0-liter V8 engine. 416 horsepower[*]. 0-to-60 in 4.6 seconds[*]. A track-tuned suspension. It's just scratching the surface of a passion for performance that's as deep as its racing pedigree.
When it comes to delivering heart-stopping performance, the proof is in simple numbers. 416 hp[*] and 371 lb-ft of torque[*] from the IS F's 5.0-liter V8 engine help deliver a 0-to-60 time of just 4.6 seconds[*]. It's engineered to enhance high-rpm breathing, so while the driver gets a crunch of power down low, it also keeps building as revs rise, for a sense of unlimited acceleration that can't be measured in numbers.
To satisfy their craving for hardcore performance, a small group of rogue engineers created the IS F between their regular assignments. But they weren't satisfied with just creating a monster—that monster had to be legit. So they tested the IS F at some of the world's most iconic racetracks, including the IS F's home circuit, Fuji Speedway in Japan. By the time testing was complete, the result was not just a car these engineers wanted to make—it was a car these serious enthusiasts wanted to drive.
