Im assuming itll work fine....but i want to make sure before i plug it back in.

It depends - Turn on the ignition key and plug your Gryphon back in. Note your HEX code! If it is different and it probably will be, there are two options:

If you do not have your custom tunes yet, you should be fine. You should be able to reprogram the truck to any of the canned tunes. But, make sure Bill and Corey get the new hex value so that your custom tunes can be written properly! Change it in your UserCP too.

But, if you already have custom tunes and the HEX code is different, then they either won't work properly on your truck or you won't be able to program the PCM at all. Contact Bill so that he can modify your tunes, which you will have to "re-download". In the meantime you can drive around on Level 0 and use the unit as a gauge. (Bill should be able to "fix" your tunes rather quickly, once he knows your HEX).
