The first Thundermax versions were not auto tune, however when they came out with the A/T module you could purchase it seperately. I would call Zipper's and see if they can be of any help. The T-Max basic can be dyno tuned just like any other system but finding a shop that works with them will be your challenge. The bright side is Zipper's location is not that far from you, just south of Baltimore, Md on route 100.
