Hi, I was wondering if an HKS EVC or Greddy Profec could be used to increase the boost in an A4 1.8T? Someone on the A4 board said that it "CAN'T" be done on Audi's and that the only way to increase boost in an A4 1.8T is by using a chip. He used a lot of CAPITAL letters and !!! as if he was yelling ;) Thought I'd post the question here and get some real answers. Best Regards, Ali
