I can't chime in on meth, but E85 should be logged for the first few tanks to make sure everything is happy. Start with 25-35% and see how it runs. Don't exceed 40% on the stock LPFP, everyone's car is different so only logs can show how much wiggle room you have with E85 without uprading the LPFP system.

My car seems happiest at 40% E85, and the rest 93. That was before my clutch wrote me a letter saying it wanted to be replaced if I was going to keep abusing it.

Read through this, and the other FAQ's on N54Tech for some good pointers as well.

Definitely get the logging stuff down pat before you start doing a lot of mods. It is essential.

Correct, however a few port injection kits have been brought to light with more than enough fuel delivery

I'd say anything over 400hp to keep things running smooth and not stressing your fuel system. All depends on your logs, mods, car.
