Just ask for help man, we cant help if you dont ask for it.

First, what FS (V1 or V2)? If its a V2, do you have the absolute latest software downloaded? Look here: EFILive July 5th release and download BOTH V7 and V8 if you have a V2, you need the firmware in the V8 download. If you have a V1, just the V7 download is ok.

If you have a V2 then you'll need to upgrade the bootblock and firmware to the latest. Also, have you tried a different laptop to pull the tune? Has your truck ever had a handheld used on it or a Bullydog that goes in-line with the engine harness?
