Just purchased a 2010 S5 convertible with approx 15k miles. Want to have it tuned for a bit more performance. Warranty is up in March '14. I have read through numerous post, but I cannot find one that compares the different companies and their tunes. If someone wouldn't mind sharing their opinion, that would be great. I do not plan on running on a track and will always us 93 octane. Does a tune with a smaller pulley help? Thanks!
