What are the biggest injectors the stock computer can control?
What are the biggest injectors the stock computer can control? I am doing a turbo build swap on my Buick with a 5.3 and was trying to figure out if I can use a F-body PCM or do I need to go with one of the expensive setups like big stuff 3? I plan on running on E85 which requires about 30% more fuel than gas for same power so by calculations I would need around 120lb hr. injectors for what I plan to run.
i have 80lbs at 43psi injectors turned to 80psi and im making 600whp on e85 at 60% duty cycle. A aftermarket fuel pressure regulator with a boost reference with higher fuel pressure would be a better idea for you then trying to shove the biggest injector in there.
I know I just looked on Summit. They sell a boost referenced non return inline regulator that is good up to 75 psi for about 100 bucks. I will likely go that route with a Summit 450gph inline fuel pump. The 6765 turbo I am looking at is rated at 900 hp but to get that it likely would need to be on kill at 35 psi. I likely would see around 700-750 at the flywheel at the boost I would be running. What brand 80 injectors and do they fit in the stock or fast intake.

now im only at 600whp and im going for the 800whp mark here soon once my new shortblock is done so were see how well my fuel system is.
always wanted to see the idle quality on these,they are flipping huge! and would work with the stock computer and be a direct replacment
160 lb Bosch High Impedance Fuel Injector

I have these, they make my car idle like almost stock. They aren't cheap but they are worth it. I would never go to a low-z injector ever again.

$153.87 from fuel injector connection. Is there such a thing as too big of an injector? Im looking for 1k rwhp from my 6.0 build set on kill with a street tune of 7-800 and I don't want to be maxing out a smaller set of injectors
Here is the link for them and a few others.

These guys are awesome to deal with. They will send you all the information to make them run. So there is no guessing. Plus you do not need any driver/ resistor boxes, these are plag in play. And they play nice with the stock PCM.
