James brought the Challenger back to Dale's house on 8/25, basically one week prior to the beginning of hell week, for another test and tune session at Tulsa Raceway Park. In addition to having the headlights installed in the fiberglass front end, he had a set of steel doors fitted as well, so that he could switch back and forth for the drives. After making two Drag Week trips with Dale in the Gremlin with lexan windows, he really didn't want to deal with that again. Once the car arrived at Dale's, it still took Boone and James four hours of tweaking to get both sets of doors to fit properly and interchange without rubbing somewhere.

The test session didn't go well for James and the Challenger, between James learning to drive the car, Dale's buddy Kelton trying to learn how to tune and download the data acquisition, and Dale preoccupied with his own ride, they only got one decent pass on engine only.
