Audi Q2 (ea888.3) Stage 3 tune

I have a stage 3 tune IS38 on my Audi Q2 but it doesn't perform as intended/expected. Can someone help with figuring out the issue? I have a tuner willing to work on the car but need guidance.

Happy to pay a little bit if the issue is diagnosed, but I can't pay a full tuning price as I already paid my tuner.
