The only thing here about the Six Liter Tune is that it is IDEAL for a 5.0L engine but for the 5.8L engine the timing might need to be a little less than what is called for. The rest of the Six Liter Tune is the same for both. Listen for any pinging if you add the extra timing and either retard it slightly or add higher octane fuel to utilize the extra timing for the 5.8L.

you took the words right out of my mouth. or off my fingers? anyway, what this guy ^^^ said!
