Normal driving and P0191 with low rail pressure.

Have a ‘13 335is 6mt. First time trying e85. Put 5 gallons of e85. Flashed tune. Notice on WOT in 5/6 gear transmission was slipping. Never had this happen before. Also it sounded like boost was going in and out and according to the log i can’t determine what the issue is. Flashed off e40 tune back to stage 2 93 tune. On mhd only.
