So according to this thread, nobody on here is full E. I'm on Full E85 on my LDK SS sedan. For me to run FULL E85 I had to only get a zzp bigger fuel lobe cam. Just the 250 dollar one, not the actual upgraded cams for 600 you don't need that.
You can still use oem injectors on stock turbo and just the fuel lobe cam but you''re limited to 6500rpm rev limiter at close to sea level.
As of injector seals, only 1 needed to be replaced due to the seal being fucked and letting exhaust gasses past and the end of the rail being black. So I put e85 safe ones on and the color is black for the E85 safe ones.
So on to tuning, it's gonna take awhile. Dail in your MAF to 91 Stoich really well, Set your DAL's and WGDC to match your desired boost level and air. Figure out the % of Ethanol content in your jug/e85 station and have your tuner do some math and add that more % of fuel to make up for the e85. The tuning will take awhile and the Injector constant will need to be tinkered with alot. For me to achieve full E85 with 25PSI of boost and 33lb min of airflow was to bump up the fuel rail pressure but do it little at a time. I'm at a maximum of 2450psi
You should really get opels though. Makes tuning easier and you can set your rev limiter to 7k which does make a difference in some races lol.

I bet your car drops so much fuel pressure on spool

Wait, what? If you weren't tuned by Term I would say get a decent tuner. But that sounds wrong to me. I'm running e47 on the 6758 but I'm at 5,400 feet which helps. Still, I was running out of fuel on my dyno run where I made the numbers in my sig. Which is why I am upgrading my fuel system this winter. Opel injectors and Stage 3 cams. And custom 5th injector because I wanna run full e85 again lol
91 octane is also the highest you can get here.
But as KMO said, mixing is easy, you'll get used to it quick. Just guesstimate how much your car will take on the low side, and fill up 50/50. I also always carry a 5-gallon can of E85 with me so I never run out.

I'm at sea level and Term told me I was maxed out on my fuel. I'm not a tuner so I don't know. LOL all I know is he said I would need cams and injectors if I want to mess with e. Oh well, I'm not power hungry and the current power my car is making is enough to break v8 hearts and be reliable so I'm pretty content at this point.
I dynoed at 1129ft on E25 but had the meth to help and I had to up the fuel pressure to keep the injector timing in range

I plan on driving 12 hours each way to pick up a couple barrels of E in the spring. You have to see the the power difference for yourself. Plus E keeps EGTs low so is better for the engine you just have to watch IDC and not a crazy spool to go easy on the trans

I have a truck and just fill gas cans 1/2 and 1/2 after verifying e content, and fuel the car with cans. That way I don't even have to mess with guessing how much I have left. The cans are perfectly mixed. Just my 2 cents.

Ok, so having a boost ramp is not an issue for me because I want the tranny to last as long as possible. What the issue is for me is the fact that the highest octane available to me is only 91. So as u can imagine my timing is incredibly low. It also gets to 110+ degree F out here in CA during the summer time which doesn't help out at all. So even though I have a fully bolted 6758 zfr, my buddy with a fully bolted e47 ko4 turbo can put a car on me. 
now mind u my current tuner is Term2 so the guy knows what he is doing and my buddies ko4 balt on e47 is Trifecta tuned and has no back seats or spare tires plus I usually always have at least half a tank of gas n my girl riding with me cuz shes into racing too. Lol

No, he's actually around 6 ms around 6300 rpm and no fuel pressure drop. And that's moving 33.5lb of airflow.
The tune isn't easy to accomplish on full e85, and there's really no power difference over e47. So stick with e47 in my opinion. There aren't that many LNF tuners out there with as much experience as me, and it was a chore to tune SlowbaltSS's car on full e85 with stock injectors.
