Well I had planned on using the tunes I have aready ordered for the next 6-8 months or so and then just before I expect to get the charger, go ahead and order the custom tune for 93 on the charger. Then I can just upload it to the truck after the install is complete.
I think that way would be no waiting on tunes after its installed and certainly no shipping of a PCM and being without the truck for an extended period of time.
That and keeping my business with PHP would be ideal too
