I use Chevron Techron Injector Cleaner in all of my vehicles without anything but positive results. I tried Lucas Injector Cleaner and could not see a difference. Then used Techron on 2 tanks later and I could feel the difference. I have almost 9k miles on E85 with zero problems.
Update:
I was told that the A/F lean condition was not that bad enough to be concerned.
The coils are definitely noticeable around town and midrange passing on the highway.
The fuel tested 85 on the mark

Granateli has dyno results of iirc 18hp and 22 ftpds on a stock motor and 30+ hp on a SC.
Tuner is telling me that my car is running lean on E85 due to the Granatelli Ignition Coils that I installed on my car and that I should go back to stock. I find it hard to believe. Someone please enlighten me.
