Controller is locked...probably had a Smarty or H&S on it previous.

Need to flash in a clean OS from tunefiledepot.com

Thanks so i will be able to flash it?

[2007 5.9]

Yes...need a clean tune to flash, but it should flash no problem.

Be SURE you change the VIN BEFORE you start the truck after flashing or else its christmas on the dash.
