All of that sounds pretty good. If you are going to go full E85 and take advantage of it, you might be pushing the limit of the stock internals. I'm running the EFR 6758 at 24 psi on 93 and am moving 49 lbs/min and holding strong. It sure is a blast.
Also, I don't think you need the pro version, the standard version works just fine as that's what I have/use for my tuning. The pro version lets you attach an external wideband for data logging but the LNF already has a wideband built in so it's not necessary.
