hey whats up im new to audi and i have a 2000 s4 and a couple of questions

why does it shut down while brake boosting?

is there a way around it?

wheres the best place to get parts form?

and when i upgrade my turbos should i get twin ko4's or go for the single big turbo?

 

you could go to www.lltek.com. And i would personaly go with a big turbo kit if you are mechanicly inclined but if not then i would go with the twin k04s.

 

and if you are going to go with the big turbo kits then go with a garet.

 

cool thanks for the info
