This is a proven set up, i thought i proved that a year ago.
I do have plans for bigger injectors and a real ems but i like to see what i can do with the simple stuff. Also...my main focus is my civic so until im done with it(mid summer i would assume) the 240 will not be getting anything new.

Log your duty cycle. 550's are not enough for 400 hp, this side of completely maxed out at 3 bar. If running 4 bar then you'll have enough. You can think all you want, I know what duty cycle 50lbers/550's/Sti/60lb/615cc run at at 18-22 psi @ 3 bar of fuel pressure as I've personally logged multiple setups with these different injectors on different tunes.
Also you can't say 'oh it works great look, 25 psi on 110' because I know for a fact your setup is maxed out with a 1:1 regulator then, and at point your injectors are simple just dumping fuel. Thankfully 110 is pretty hard to detonate, and at that level you're not really making a ton of power. Try doing that with some big power and you'll have an explosion. (not to mention now you're on the level of 5/16 OE lines being to small)
Running injectors at 100% duty cycle 'to prove a point' is nonsense to me. But if it works cool. I'll reference you to multiple guys who had injectors literally 'burn up' and cause failure
