Ok its a bone stock 6.0L with everything from the 4.8L on it. The truck kept hitting the speed limiter on the pull so it only ran out to about 4900 RPM before shutting down. It Made 257.95HP and 304.00FLBS. Still 4.8L tune, I will be ordering HPT tomorrow. What do you guys think?

Once the tune is right (might take a good while if you're new at tuning) it will get a lot better.
I hope so. I'm planning pretty much the same mods as the truck Nelson is doing now. Then moving on to a turbo.
