I've got a 2020 3.5 Ecoboost I recently converted to Flex/E85 with all the supporting modifications. I got a very conservative timing advance for the flex (5 degrees) and was about to make a dedicated E85 tune. I previously raised all my cylinder pressure limits for the flex tuning and hit about 600 torque. I didn't know with the increase of timing for the dedicated E85 tune if I should calibrate in the pressure limits with the possible increased pressure from timing advance. Also, if there is anything else I should be concerned with, please let me know. I'm still decently new to the tuning. I do know that around 600 torque is about my max I should request as a driver demand due to the rods and pistons still being stock.
