Hi there,
First, I need to know who you are.
If you e-mailed your HEX code to me, your order has been put in queue for Bill to work on your custom tunes. Orders are handled on a first come, first served basis, so if you only recently ordered your Gryphon, there are other customers who will receive their custom tunes first.
When your custom tunes are written, you will receive an e-mail from Bill. Downloading Pegasus was great; all you'll have to do when your tunes are done is to plug your programmer into your computer using the USB cable we provided. The instructions will be given to you, but if you'd like, you can check in the Pegasus FAQs section, where the steps to download your tunes are outlined.
