2003a4avant

My sister recently got a 2003 avant that has some significant mods... She doesn't really know the car she bought other than she wanted the cleanest interior she could find. I told her I would help her out with getting the maintenance done. More specifically the right maintenance. I will be taking it to the same,highly regarded mechanic who apparently knows the car top to bottom.
I will find the list of mods but from what i can remember...

S4 brakes front and rear
Bigger turbo
turbo timer
2.5" exhaust
control arms
new suspension (i believe s4)
Lowered
Short throw shifter
Theres much much more and more specific.

Basically what should i expect from this car?
Does it need to be constantly tuned etc etc.

Thanks

P.S. The deal was I do the maintenance and I can take it out anytime. I thought that was a good deal since she pays for the maintenance and I get the satisfaction that everything is done right with no regard to cost.
