OFF TOPIC After Market Car Tuning Modules

[TigerG505]

I'm considering ECU/OBD tuning an A7...has anyone done this to their car? If so, any recommended vendors? Appears to be a lot out there...APR, GAIC, RaceChip, Stasis, SKN, etc...Doing it for performance and would ideally like to increase from 310 to 415hp (same as S7)...may be willing to add new pulley if necessary, but I'd prefer module-only (that can be removed) since under warranty for another 75K miles...
