I just bought an '03 RS6 and have been looking around for ECU upgrades but most are in the 2K-3K range which seems ridiculous. I did find an ECU upgrade available from Upsolute which is much more reasonably priced and offers about the same power and torque increases as the expensive upgrades. Does anyone have this or know anything about it? Thanks.
