something's wrong with you calibration.

i'm using mbar as vacuum/boost indication... so at 2104mbar something is pretty bad.

your ignition table is going mad there (jumping from 17.25°BTDC to 33.75°BTDC) and your injection has spikes there.

since you are going very fast through that area in smaller gears, the effect is showing in higher gears, since the time you are in that area is longer, and "errors" occur.
