I tihnk above 60%/40% E95/93(91) without flex fuel wires will trip ecu sensors. I dont even think our fuel pumps can handle it 100% without maxing them out.

This is not true. You can do 100% E85 with BMS flash and a JB4 without an upgraded fuel pump. With FBO and larger turbos you will need upgraded fuel pump. The pump is at its limits with stock turbos and 100% E85, but it can still do it in most cases without lean outs as I understand it. If you need upgraded pump you can source a Walbro E85 pump for $180 plus $20 of fittings and that solves the LPFP issue. There is a DIY out.
