Eboost not working after stage 1

Recently I tuned my 2020 330e stage 1 to 400hp 700nm

Now when I accelerate it doesnt use eboost anymore, even not in xtraboost sometimes it does it but only a split second

Tried everything : low battery, high battery, every drive mode, sport transmission,…
The electric engine works cuzz i can drive electric

I noticed that my sportdisplays show 400hp but only 480nm however it has 700, they forgot to change that or so. When I accelerate it instantly goes to max.

Could the eboost issue have something to do with the dme not knowing the torque?

I contact my tuner, they will help me with the sportdisplays problem, but they said that their tuning process doesnt change anything to the electrical engine.


Anyone can help me wit this?
Tune is great but a little bit useless without eboost.
