unfortunately the shops for subies in new mexico are a little scarce.there are a few shops i know of that do great work with other cars including anything imorted but i can't vouche for their work on subies. however, the subaru crowd in new mexico is a fair size and there are many individuals who do great hand work for subies. having driven subies themselves, they know and understand our vehicles very well.
they also happen to be a very nice group of guys. there are subaru meets and cruises once every two monthes. just had a subie bbq last night in fact and the big cruise is on july 15th.
aside from subie mechanics we have some excellent tuners in town and 1 awd dyno open right now with another in the works. there is a fellow here named Cameron who tuned my car. goes by 06rexwagon on nasioc. he's not big time yet, but he's got a pretty good name for himself in new mexico. tuned ALOT of subies here and does excellent work, not to mention he is a really nice guy. he himself drives a 06 wrx with the same setup as mine minus the front mount plus meth injection.
Nathan(nmyeti) from ex-turboxs tuner also resides in new mexico if you desire his professional services. shoot me a pm if you decide to come down, i work 12 hours 7 days a week but i'm more then willing to spend the time i have away from work to help you out and point you to the people who can help take yur subie to the next level.
