the stall on the converter is 3,400 It is an Edge Racing 9.5" STR (street) converter built knowing I would be spraying nitrous at the car in the future

Not sure I know what you mean by your paragraph #2. The ONLY thing I changed from run 1, to 2, to 3 was the launch rpm on the 2 step. Thats the only different change I made and to me, the change was indeed a small-change. I shifted at the same point as best as I could. I went from 2-step launch at 1,600 (1), 1,800 (2) and 2,000 (3) and then I footbraked at 1,200 knowing that the car would not creep (4). Smaller changes than that?

The car does push forward around 1,700 footbraking it. It did it on run #3 if you wanted to watch the very short video of it happening, check my youtube videos: https://www.youtube.com/user/IROCZma...=dd&shelf_id=4
