I tuned my car shift points based on my own tire size, gear ratio, and speed. So basically I used a gearing calculator, figuresd out at what speed I'm at my desired rpm, and shifted about 3mph sooner than the table said. So of I'm at 6100rpm at 70mph in 2nd, I'll shift at 67. It's proven right so far. If I hit the limiter, I back it off 1 mph. If I don't I try moving closer. It's trial and error.
There may be better ways but I was comfortable doing it this way.
