Just wanted to say I was in the Washington D.C. area this past week ( I live in Denver Colorado) and went to check out the Altered Atmosphere shop. I must say those guys are amazing I went through the front door expecting to have some guy just brush me off as a waste of time customer but Clinton the shop manager introduced himself and proceded to show both me and my father his shop for the next hour answering any and all questions big and small. He gave me the full tour showing off all the cars dyno and machines for creating all of there products. They have made me a customer and I am going to buy all my future Z forced induction products from them, I am a service advisor for Chrysler and have a good knowledge of cars but the kind of know how and experience these guys had was amazing! Its no wonder that people from all over the country send there cars to them. Just my two cents I was pretty impressed.

 

Cobb Tuning in SLC is mucho closer to you.

 

AAM reputation isn't that great with the mid-a folks since it is all MD/DC/VA. Depends on who you ask. Some will say great, but many others will tell you to stay away. Just do a search/research if you plan to do any business with them.
