Batleground is in Smyrna on Atlanta Rd and boost solutions is out of bussiness. Also you can try Knowledge Performance in Kennesaw, Subaru of Gwinnett in Duluth, Topspeed in Alpharetta, Dyno4mance in Calhoun. All have AWD dynos including Batleground.
Boost Solutions screwed a bunch of people over and then the owner jumped ship and split town with cars still in the shop. Batlground has done some suby work. Knowledge were alright guys when we had our dyno day but I dont see any reason to go to them over Subaru of Gwinnett or TopSpeed.
