7875 + 5.9 + E85 + Megasquirt

Swapped out the O2 and it still goes really rich (10.1) when going into boost. The good news is I got the boost controller configured properly and did a couple of hits and reached 11.8psi at which point the AFRs came back into normal range. Inj Duty cycle at that psi is about 85% so that’s probably as far as I should push these injectors.
