how to get reading out of HP at rear wheels PID

i have a 2004.5 LLY w/ 5 speed allison. i have the HP at rear wheels PID validated and it does not have an X through it. so it should read during scanning. why does it always read 0 HP?

1) Before logging, using the scanner software, go to File->Enter Vin:
Put in the kg or lbs of vehicle:

2) After log, use Notepad.exe to open the log.efi file and manual enter the GVW in kg. such as
To enter a 1564.894kg, enter it as 1564894 with no decimal points. Reload the graph and the hp data should be there.

thanks alot i just couldn't figure that out.
