From what I understand, if your maxing out your injectors you'll need larger (60's) for safety reasons. I dont think the 60's alone will add any more power. They would allow you to run more boost, but that 2.80 + 4# lower is spinning that eaton pretty fast.

What does your tuner say, you will be very close yes, for the most part they say stock injectors are good to 600hp but then again, every car is different. I would check with your tuner so you don't waste $. Great numbers though, can't wait til I get there.

based on your mods list you are probably maxxing out your stock injectors. It's not a matter of how much power you get from injectors.

Injectors are just a supporting mod, they do not yield more power, they just increase the amount of fuel that can be sprayed.

So larger injectors will prevent you from leaning out, assuming you have the tuner tune for it. You cannot change injectors and then just start that car - that would be a disaster. When tuning the car you have to chose which injector size in the parameters. If you have an XCal 2 you can change this on the fly, but you would still need some adjustments after changing injectors for WOT.

Thanks guys for your info. Guess injectors will be my next mod lol. I dont know much about the xcal2 on messing with it to change for injectors, so ill prolly let the turner himself mess with it

I have seen People use a kenne bell BOOST-A-PUMP instead of going to larger injectors. Would it be ok to go that route instead of 60lb injectors? It's a hell of a lot cheaper too haha.

The boost a pump is for increasing the workload of your FUEL PUMP, not the injectors. The boost a pump basically saves you from having to change out the pumps or entire system for a while (unless you go crazy 800+ rwhp).

Boost a pump and larger injectors work together, stock injectors can only spray so much and the boost a pump will push the stock injectors to max.

no, you need both usually. If you are maxxing out your injectors, you can change them and then if it's leaning out that means the fuel pump is at max load, then you need a boost a pump. 99% of the time you need both.

The boost a pump increases voltage to the fuel pumps to make them pump more fuel over stock (in rear of car)

The injectors spray the fuel into the combustion chamber (in front of car) and even if you have a boost a pump only, the injectors can max out. The more lbs the injectors are, the more fuel they can spray out at once. But if you don't have a boost a pump and you max out the fuel pumps, then the injectors won't have enough fuel to spray.

ahhhh I see! So naturally if I went with injectors I would not need a BAP?
