BM3 antilag malfunction

I tried out AntiLag on my 2015 BMW M235i 6MT on the OTS stage 1 93 octane map, once I hit the accelerator I heard a boom and the drivetrain malfunction came on and threw those codes (108A01,121001,108A10,120408) I was in 3rd gear about 3.2k rpm, I was still able to limp the car home. It's about midnight now and raining so I wasn't able to get under the hood to see what happened but anything thoughts? Current mods: stock car, stock chargepipe etc.

Very high change it was your charge pipe that blew off. Even at stock power they blow off that's why it's a recommend 1st upgrade for our cars, let alone when tuning it at any stage. I would check that first.

The stock charge pipe isn't even good enough for a stock car, start there.
