My lamborghini gallardo LP570 2009 never had a problem with its acceleration but has lost power since the repair of the automatic gear. The car takes a long time to shift from first gear to another

1. Its power has decreased from the original
speed. How do i solve this problem?
2. There was a problem with the E-gear (fixed) and
brake lights were always on (fixed) but did not
affect the speed of the car and can be drove with
manual gear
3. The last service was for E-gear & brake lights
and it was solved.
4.  While driving after we left the workshop, i found
out that it was not fast and lost power from how it
used to be. A honda could easily beat the lambo
because of the lack of power.
5. Then, i sent to another workshop and changed
battery brand VETRA and opened the spark plug,
only 5 was moving and 5 was not.
