Hi there everybody I drive a F40 M135i 2022 model. I recently got my car a stage 2 remap and downpipe alongside a new air intake and a femto unlock from a tuner who is quite reputable near me.

They used bm3 to tune the car and it sounds awesome and way better than stock. However the performance doesn’t feel right they claimed the car now made 360 bhp coming from 306 stock and also made 550 n/m torque coming from 450 stock i believe.

When driving the car it doesn’t feel quicker at all it actually feels noticeably less grabby than stock and actually feels the same but with less punch. When timing the 0-60 times it felt exactly the same as stock which is disappointing. What could the tuners possibly have done wrong? Why doesn’t it feel right?

I will also attach the dyno graph as i’m not too sure i understand if and could do with some help on it.
