what are some mods, if any, especially for a 2002 tiptronic S4

 

ecu flash is the way to go if u want hp and tq, plus the drop in filter and the cat back system borla or miltek is the best

lol

 

I already have a Revo flash, UUC cat back, milltek downpipes, and forge DVs, and a K&N airfilter. I am thinking about adding RS4 intercoolers and ARP bi-pipe, what else is there besides for new turbos and suspension?
