Big injector help

you running the stock turbo? if not then what? if you're on the stock ct then 700cc injectors might be a little overkill. 550 injectors would do just fine. tell us the rest of your setup.
No problems. Just the safc is kinda eh. Maft pro would a lot better. Even a maft gen II would be better than safc.
550s are cheap too used. Just get them cleaned and flow tested.

I ran a Lex AFM + Denso 680s with a Neo for a while. No real issues. The SAFC will remove up to 50% fuel (someone correct me if I am wrong here). I have an AEM standalone now and sequential injection, but the LEX AFM and 550s are perfect for a CT26 setup (any trim). I currently have a NIB set of 550s FS. PM me or find my FS post.
for what its worth, I am runnig an AEM with E-85 and 720's with great success with my (61mm) gt35r! I'm out of fuel at 20lbs, but I will be running some 1350's this summer 
go with 550s if you are just gonna run a CT.
id get 680s if you gonna plan on gettin a T61 bolt on or even go to a T4 turbo in the future just so you'd be future proofed.
Could also contact Juhani on SF and get 550s or close to it made then when you want bigger ones just ship em to him and its like 20 bucks and injector to get them resized.

Even though the SAFC can remove 50% fuel you also have to understand that it pulls ignition timing when you do that..
Ill be running 850CC injectors on my car with Stock CT26 very soon

Running too big of an injector can be a bad thing.
Like 850 with stock ct. You will never get past 300 which means your using less than half the injector. Not good.

Not with megasquirt, speed density, and E85

Oh and I will be passed 300 to the wheels on stock turbo

E85 is totally different. As you almost double the fuel. Which on gas would put your injectors at 425 which is about stock.
Doubt it unless your still running n/a high comp. Whp with 8.4 mega doubt it but prove me wrong.

Im running original 9.1:1 compression on top of that with the head decked 10 thousands with a stock thickness HG (1.37mm if I'm not mistaken compressed)
14 lbs on the stock turbo with E85 will get me to 300-320 to the wheels..

Why run 850s? So you can say that you have 850cc injectors? Even with MS and E85, what's the point on a CT26 setup? Seems like a lot of work to retrofit a fuel system just to keep the stock turbine. You make a point regarding the timing, but the SAFC doesn't really "pull" timing, it just makes the ECU "see" less airflow and therefore advances the timing at part throttle. All the more reason to use injectors that are matched to your particular setup when using piggyback fuel management.
I don't see how these types of answers are going to help the OP. He's not running E85. He wants to stick with the stock turbo setup (or close to it). How about offering some sound advice instead of jacking the thread? Running huge-ass injectors on a moderately-sized turbo sounds like an awesome idea until you try to tune the thing, then it's not quite so cool. Just trying to offer information to help the OP make an informed decision and not waste his (presumably hard-earned) money.
My point is this: Reg Reimer of SOGI came up with the Lexus AFM/550cc injector idea over 13years ago. The idea is sound. 25% more airflow and 25% more fuel to raise the boost limit. I'm not a big fan of the special adjustment bolt, but that's where the piggyback comes in.

Please tell me how you can make more power on a semi-stock setup for less money and the same amount of time invested without using a FCD or a VPC ($$$).
