I had similar symptoms of the car all of a sudden running lean on e85. My fuel trims went extremely positive trying to compensate and eventually threw a lean code. I have similar mods as you: JRSC, DT flex fuel kit, DW injectors and DW Map sensor. I initially thought it was an exhaust or intake leak somewhere but that checked out okay. I ended up sending an idle log to zach@delicioustuning and he determined my ethanol content analyzer (black box) had gone bad. We replaced it and we were good to go again. I would look into that as it's a pretty easy thing to rule out. Good luck!
