I am so done with this forum. I have posted several threads asking of input from others interested in the S5, and the only thing I get on the forum is ECS Tuning trying to sell something (which may be a completely valid and valuable product), and another person trying to get an answer......but there is never a response. So, there are no Audi s5 drivers interested enough to respond, or there is no infrastructure with experienced Audi mechanics to respond. Caddy sites were great, and Corvette sites were great. I am removing this as a site that I check out. Bye.
