Not working properly

Hello. I installed a 110hp TDI in my 3er Golf. However, I feel that it's not running properly. I can see this because when I'm driving on the highway and in 5th gear, when I give it gas, it pulls well but feels sluggish. Also, it feels like I have a 90hp engine in it. And sometimes, I feel a brief jerk in the steering wheel, like it's pulling hard for half a second. I've already replaced the ECU, the turbocharger, the air mass meter, and the timing belt, and I've adjusted the fuel pump, but it's still the same. I have an adjustable chip in it, and when I activate it, it runs better, but not as it should. Can anyone help me?

with this error description difficult.

Search the error database for the correct values for your engine code and verify with a diagnostic tool.
Please review all entries in the error database for your engine code.
First, check:
- Error memory
- Air mass values and
- Loading pressure

at full throttle, at different speeds, and with a minimum of 3s of full throttle before each (2000min-1, 3000min-1, 3500min-1, 4000min-1, 4500min-1).
Please measure all values without attached chips, as they are otherwise less comparable.
Okay, hier sind die Werte, die du angefordert hast:



You wrote that you adjusted the (fuel injection) pump, how did you control the start of the fuel flow or the start of injection?
Since you don't mention other noticeable issues like chewing or nail biting, it's difficult to further narrow down the cause.
If all values are within the normal range, you should also consider trivial issues such as clogged/old fuel filters, etc.
