Rocking the "Stg1 Aggressive I8A0S v301.ptm" map w/ 93 octane, about half a tank of gas left.
Couldn't reproduce the misfire with the BMW Tech doing a ride-along, but the car stuttered slightly and he was saying it's likely the fuel pump not being able to provide sufficient fuel that the tune is demanding, and not a problem with the injectors...

He's installing the catless DP's for me today and I'll flash Stg2 tomorrow, see if I still throw codes.

Anyone know the specific values the maps change? From what (stock) to what (stage1). The tech said he might be able to better diagnose the issue if he knew what the actual values were. I could datalog for him, but what my car outputs isn't necessarily what the values SHOULD be, so he can't tell what's wrong.
