Is my timing malfunctioning?

What does this mean if your timing indicator goes back (retard) when you rev the engine?

I have to advance my timing so it will go back to 0 degrees at Wot.
If I set the timing to zero it will retard and I loose power...

I did a search and did not come up with a solution although I've found similiar senarios of wondering timing

What's broken?

Did you unplug the tan connector under the passenger side carpet?

Sound to me like the ecm is advancing it still.

Disconnect the tan wire
start truck
set timing to 0
turnt ruck off
plug tan connector back in
remove ECM B fuse to reset ecm and clear codes.
enjoy.

It's doing this with the tan wire unplugged.

reconnect the tan wire, and reset codes
