Porting the MSD will help and getting head work done is ALWAYS money well spent.
You've mentioned that e85 is available so once you decide on how to move forward, definitely get the sensor and tune for it...it's like liquid crack for our motors.
It seems you know what you are doing tuner wise but I would take a slice of humble pie and ask EFX, Pray or GPI to take a peek at your tune just to double check, it seems like the cheapest remedy if you overlooked something. Their are plenty of other tuners out there but I would gravitate towards the guys who are on the fast list, for obvious reasons.
I know your question was the concern about the mid range and not the top number, but racers don't live at 3500 rpm so I wouldn't sweat it too much. Good luck homie.

Good to have feedback. I agree my build is not perfect. In my case a 103mm TB would work fine then….to note my 87 mm is a Katech Ported one…
Before having to pay a tuner to tell me stuff I already know, I would prefer to spend money on parts...Who can port the MSD by the way ? If after the parts I still have issues then I'll consider it...
3500 rpm is a common rpm in AutoX...on roadcourse not so much….
