“My 1969 Camaro with 383 small block and a Holley fuel injection system has had drive-ability issues for many years. I had been to a few different tuners with less than optimal results. Doug was able to get the car running perfectly. He really spent the time and effort dialing the car in. It now runs like a new car. What an amazing transformation”
