For now, you can use the Gryphon Gasoline Form on the Order Form website page. (I'm working on new order forms.) Don't select anything for the product you'd like to order, but in the box below where you select your custom tunes, just put in a message letting us know that you bought a used Gryphon and from whom it was purchased. The only reason for this is so that we don't have anyone purchasing custom tunes for the Evolutions.
We can also make sure the serial number is transferred to you. Custom tunes are $50 apiece, and you can purchase 1, 2, or 3!
If you have any other questions, give me a shout, and :welcome3: to the forum! Glad to have you here!
