use map 7 instead of map 5. Your right on target with the boost targets.

Also, do you have a LPFP upgrade? If not, lower e content or get one. Your lpfp dips low in the top end.

Is that even safe? I have no lpfp upgrade.

Time to get one if you want to keep running that much E. Stock pump will be on its way out soon.

Low pressure pump is still dropping a lot in the higher RPMs but your high pressure is still okay; however, if you LPFP is that weak it is just a matter of time before you start having issues. Two options: 1. Replace the LPFP with something like a Fuel-it Stage 2 or 2. Run a lower E concentration.

Just posted a WTB fuel-it stage 2. Lol. Was planning to upgrade cp but changed plan.

Your LPFP is suffering, either reduce the E85 mix or get Fuel-it stage kit.
Also dont count on the virtual dyno for accurate HP numbers
