If using a shift light, make sure you compensate for the delay in time, from the time you see the light, to when you react to the light, and when the car actually makes the shift, and set the light accordingly. At 5 or 6000 RPM you can be 500 RPM past your shift point during that time.

Ron....welcome to the forum.....a manual valvebody will NEVER and I repeat NEVER be as consistent as a PCM shifted tranny...period. Your shift techniques may be all and well for a 5.0, but if you use those techniques with a 4.6 you will be looking at tailights quite often.
