When to shift?

Stretch of road is freeway, or expressway, both have CHP. I do test fate once in a while just to see how it runs up to 6000rpms. Just so I can run it at the track, or to see if it will launch and stop in front of the house but, that brought out, a guy off work to see why the noise. Neighbors are changing to foreigners and might squeal to the police.
Nothing like Hiway 12 through Glen Ellen where we lived in the 80's, down the road from Marshall's Machine Shop in Whine Country Kenwood.
Your talking about software for the car and a laptop, that I can do. What exactly am I looking for? (search bing G-tech, nothing about dyno software)
Ok I found it on the forum.
