I wanted to thank you all for your training and products. I attended your training for powerstrokes in March at the Vision KC convention. From the day I returned from your course I have PROFITED 3,000 – 6,000 a month more just off the knowledge I gained about the 6.0 powerstoke. Lets just say this, I flew first class to Kansas City, stayed in a nice hotel and flew back. The day I got back I sold a job repairing a 6.0 diesel that profited enough to pay for my entire trip. Great class, amazing book. Keep up the great work! - Jon M (5 star review found on ATG training)
