Maybe/maybe not.
As for Power-Timing, on the street;
The engine will usually tell you by rattling when you give her too much, and by being a lil lazy if not nearly enough.. In between, you get to fool around. I wouldn't sweat 3* short of ideal. You can sneak up on that as time goes by.
That Sound Good, however Will be running nitrous and 3* Is a big difference, Will start at at 30* total , take out 6* on nitrous, (2 per 50 hp) read the plugs, adjust the nitrous jets and carb jets, and go from there.
Thanks
