Quick E85 pros/cons list;
Pros: Easy power, cools combustion temps, about $1/gal less than 93.... did I mention more powa!!
Cons: Inconvenient, less fuel mileage, not readily available in most areas, requires some sort of fuel system upgrade in most cases

LNF's aren't usually recommended to run on full e85. The sweet spot for us is e47. As far as fueling upgrades, we are really limited to only 2 options. Upgraded fuel lope on zzp cams or 5th injector setup.
Stock k04 LNF's on e47 will be perfectly safe with no fuel system upgrades, only must is a fuel pressure increase on the high pressure fuel pump. Depending on the car, some LNF's can get away with running full e85 without issues with big fuel pressure drops, others can not.
A small turbo upgrade like a bnr2871, or k04+ can sometimes get away with no fuel system mods when running e47 but a minimum of an upgraded fuel lobe must be ran for straight e85.
An EFR or larger turbo running e47 MUST have a minimum of an upgraded fuel lobe and depending on turbo size and boost needs will most likely need a 5th injector setup.

Just for the record, the 05 pumps will flow plenty of fuel for 95% of the people's setups on E85. The main problem is that their failure rate is much higher than the newer pumps. My pump finally gave up on me about a month after I put the ZZP rewire kit on my car to try to give me that little bit of extra fuel. I rev my car to 7600+ rpms on the TVS and 2.7 and I wanted a little more safety cushion for fueling before going BRFPS or RSFS. While the pump was able to slack at lower voltages and 7400 rpms max fuel demand it was fine, but when I started reving further and did the rewire (not blaming ZZP at all, the rewire clearly provided more voltage to the pump 
) it just got tired and finally had enough.
