Pulled from 2nd gear to 4th. Traction off.

Had a 30ff shadow (inactive) code charge-air pressure too low. Haven't driven car in about a week. No CEL on. Car drove normal. Cleared code and went on a 5 min drive to see if everything's normal. 2013 335is 6MT 65k miles. Car is stage 2+ ots mhd map.

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.
