100 Octane
M440i stage 2
After flashing Stage 2, the engine started to show noticeable irregular behavior.
In Sport / Sport+ modes, when driving without full load, the car experiences strong jerks — it feels like the engine hesitates and then suddenly catches again.
In Comfort mode, everything is smooth with no issues.
Under full throttle, the jerks are still present, but much less noticeable — the problem is most obvious during partial throttle / moderate acceleration.
