AUDI RS4 B7. Lumpy power delivery.

[B7RS4]

Looking at any advice on slightly lumpy power delivery under power, not sure if it is the tyres, fuel pump, any ideas or checks i could do to maybe fix this? its not bad just a little annoying sometimes.

It might help if you gave a more detailed explanation of what you mean by lumpy power delivery, along with conditions at which it happens. Conditions like engine speed, hot or cold, load, service history, state of tyres, etc.
