Clearly i'm new at this. And don't know the ropes. So I've made a ton of mistakes. So, for fear of already irritating the piss out of the guys at my local shop and they that work on my car, what are some best practices, things to avoid doing or things to insure you do, when dealing with your local shop/mechanics/tuners? Is there some sort of performance car etiquette guide?
I guess it would be nice to know how to not piss off your fellow WRX owners as well, particularly those who have been down since the WRX was the RS.
