Throttle adaptation
VW Passat Variant (365)

Hello everyone. On a muffled car, the branch pipe was removed to the throttle valve (it was necessary to get to the generator). The damper itself was not cleaned, not even touched. Then, during reassembly, the pipe was put on, but they forgot to tighten the clamp. I just left the place, well, of course, the car jerks during acceleration. I  returned back, tightened the clamp. On engine operation everything is OK, idle is normal, do not freeze, do not jump. 

Do I need to make an adaptation by a computer? It feels like the car has become a little dumper.

Thanks in advance to everyone.
