Have people run e85 on stock injectors and fuel pump and if so how much mixture? If not what do you recommend to upgrade?

Yes, as far as mixtures I'm not sure I remember. Someone else can chime on that. Most people running e85 with a flash are already upgraded. Catless downpipes and an upgraded. Intercooler, intake, and exhaust. Don't think the upgrades are required but you'd at least need the custom map flashed.

Yes i think 30-40% is the safest for stock fuel pumps to handle.

I will be testing with a back end flash and 35% e85 this coming week and will give you an update.

It really depends on the "health" of your stock LPF.

I ran e30, and my low pressure pump was struggling.

Swapped out the old oem with a new one + a walbro inline255. Haven't had any issues since, and am looking to run e40 or 50.

You can run e85 on stock pump.
Just make sure you do not go over 35%.

why 35%? just wondering the reason and if you get a walbro 255 Inline, can you run higher % rate?

Because you lpfp will suffer with more than that.
If you get the walbro inline fuel pump you can run more e85
