That's it if you are using HPT, of course.

so if that table is set to 6200/6250 then I would just need to raise my shift point to something higher than it currently is.

Yes, if that's the route you want to go. I don't recommend messing with the rev limit much, as there is very little gain for most, and increased chance of damaging the motor. Valve float may be an issue.

valve float is the biggest concern. I'm running 90 lb LS6 springs and an xp cam so raising the shift point should make more power. I'm probably not going to mess with it until I get my tune a lot better. right now my o2 readings at wot are around 870 and I need to raise that to about 910, so I've been messing with the pe afr, on the last scan I had it set to 12.4 and had about 5 degrees of kr while going full throttle up a 6% grade, so I am in the process of lowering it a little bit at a time, ultimately it will be 11.5 to 12.

I am planning on doing some dyno tuning within the next month so when I am down there I will experiment with the raised shift points and powerband.
