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.

What AFR do you run the car at? I totally agree that with the lobe you'll have enough fuel up top that is no issue but on spool i bet its out of control! And the MAF airflow you stated is really low but i know that's not a good comparison point because injector constant and how much fuel is pulled from the MAF comes into play

I have him running a target lambda of 0.88 to 0.89 which would be a gas equivalent AFR of 12.9 - 13.0. Since he is on e85 the real AFR is quite different, but I find it easier to talk to most people about LNF AFRs in terms of Lambda because it's more of an apples to apples language.
