It's a good idea to increase the line pressure in the tune just a bit. The stock shift points are 6000 rpm for the 1-2 shift and 5900 for the rest.
Depending on the type of fuel you run (actually what the knock learn factor is) it will be between these two values at WOT. The Low Octane table is set for 19 degrees.
The stock 99 Vette High Octane spark table is actually set to 28 degrees at peak hp.
