At least for RS6, GIAC's tune runs lean at higher RPM's (that is where all the fun begins!) - No sense in running lean and grenading your engine.

Also, APR is running their sale NOW (March 25 - April 28) and I get nothing out of suggesting this.
Get it at PureMS.

Stay away from All German in Vista/Escondido... BAD Customer Service.
