My first tune was from bama before AM took over. It was back when my Mustang just had CAI and delete plates. I was very happy with it and I got grandfathered into the AM tunes for life. I got many updates as I progressed through my mod journey. Headers, 127450 cams n/a, then 127450 cams with non intercooled Whipple then with stock cams & Whipple. They worked to help me pass emmisions every year and while sometimes it took several tries they always worked with me until the tune was right. I would probably still use an AM tune but they didn't want to try tuning the Whipple once I installed the big boost upgrade. Once you get boosted Manuel (lito) is the man but AM is very helpful and will work with you to make sure you are happy.
