You shift when you can safely reduce the load by entering a higher gear.
Launch @ whatever RPM you feel comfortable with. I'll usually go @ 4K when Auto-Xing

What RPM's should I be shifting at for each gear? How about on the launch, what RPM should the tach read?
Shift at Pi RPM's huh? I'm not sure I can get the engine to idle that low!
daily driving no more than 3,500-4,000 at most,
for high preformance, dyno ur car and shift so u go from peak hp to peak tq if you can ie, 4K= max tq, -7000=max hp, shift so rpms will drop to about 4 k so shift about 7.2k make sense?
I usually shift at no higher than 3.5 around town and at or around 6k (cuz after that the peak hp tapers off) when I'm havin fun.
Red line the tach in first then 6,400 rpm is a nice compromise for the rest of the gears. You want max area under the HP curve.
Around town I short shift at about 3,000 rpm...
Cones don't count at Hillclimbs.
Around town i shift between 2500 and 3000 to save gas. When driving sporty i shift no higher then 6k in first then no higher then 5.5k in every other gear.
