And probably, because of the CAI, the feedback loop between the O2 sensors and the MAF sensor was unable to compensate? (That would be my guess, anyway). That CAI may be driving you VERY lean. It would be interesting to see what would happen if you took the CAI off and ran it again with E85 on Level 2.
Anyway, welcome to the forum!
