Fellow Audi Fanatics, Does anyone know where I can get a stiffer wastegate spring and diaphragm from? I already am chipped (qlcc 1.95) and am wondering how much, and what kind of an improvement this would make. Thanks, Audiman1@msn.com 1987 5000 CD Quattro (sees 1.8 bar easily, once in a while can get 1.9)
