30 lbs fuel injectors
Hello all,
I was curious to see what 30 lbs fuel injectors people are running now? I have an ancient set for Accel injectors currently that are most likely having flow issues (already checked fuel pressure, vac leaks, replaced fuel filter, o2 sensors, and checked MAF, still running very lean). For tuning reasons, I'd prefer some well documented ones vs something from fuel injector connection, as they only provide the injector flow rate. Seemed like years ago the goto was the SVO redtops, but I cant find any threads on them from the last 10 years. Any help would be appreciated.

I'd recommend Bosch III 0280 155 759 (which are what I'm running)
Largely because they have an official datasheet from Ford Motorsport

That said, you'll have to adjust your voltage offsets in the ECM to get them optimized.
Would also recommend South Bay Fuel Injectors.

I ran GM 12613411 injectors for a long time. They flow 32 pounds at 43 psi. They're a factory GM injector used on all kinds of flex fuel vehicles. Data for these is readily available online. If you get them new they run around $250 to $300 for a set. If you get them from a wreaking yard they only go for around $50 a set at most. You'll need injector top hats and wiring adapters to make them work. But those are really cheap. These probably had the best idle quality of any fuel injector I ever messed with.
I swapped these out for Holley 76 pound injectors. If I didn't need more injector for E85 and progressive nitrous I would still be using the 411 injectors.

Ok so, in my ongoing saga of trying to sort out this car, I found that the previous owner had the fuel pressure set to a whopping 55 psi on key on. Even weirder, in the ECU, they had the injector constant set to 30.91 on a 30 lbs accel injector. At that pressure, they are flowing closer to a 33 lbs injector. Would I be better off ordering a 32 lbs injector and setting the fuel pressure more reasonably, or sticking with a 30 lbs injector and keeping the fuel pressure where it is?
