Hi,

I've got e91 320d 177HP automatic transmission.

It had ecu remap to 218HP and 435Nm at 2300 RPM, unfortunately after remap, there was something like rumble/shaking/vibration at 3rd gear only between 2100 and 2500 RPM only when accelerating hard. Moreover, something more like mild metallic vibration between 2200 and 2300 RPM on 4th and 5th gear (when accelerating hard only).

Tuner said, the program was OK, tested with other similar cars, so there's a problem with the car, not the program.

But he remapped it again, decreased the power by a half, unfortunately still some rumble and vibration. He could still decrease the power, but it doesn't make sense, because we're getting close to the stock version.

So, I've got the car checked at bmw dealer and they said everything was OK with the car.

Have you got any idea, what can be wrong with the car and what to look at?
