You need tuning software or a scan tool that is capable of doing it...if you don't have access to either, the dealer can do it for you for about .5 labor, just be sure to tell them that is all you want, or they may try to do you a favor and give your PCM the most recent updates, which will wipe out your nice new custom tune

thanks bud, do you know of any harm running it like this?

If it's running smoothly and not misfiring I'd think that you'd be fine...I had a crank variation that was so far off once that the truck wouldn't even idle
