The name is Walker dynotune. They are located in Birmingham, Alabama. They have a website: walkerdynotune.com but it seems to down.
Been having more issues with my tune that I need to get fixed. There is a place in Cullman that I was going to try but I've heard a few things about this place too. It seems that they were involved in the testing for a new plenum for the 4.6's.
