Yeah I've heard the stories about the GIAC tune. My VAG-COM just arrived in the mail this week, so as soon as I figured out how to log data I'll be double checking the tune. I bought the car with it on there but the previous owner shelled out $2000 for it in April of 2012. Not sure what version it is. I haven't done much research into other ECU tunes but if it costs that much to reflash a different tune, I'd rather make sure it's not running lean and keep it in before jumping ship to another tune. Granted, if it is running badly I'll switch for sure as I don't want to grenade the engine.
