Question on installing custom tunes

[RevoErick]

When my custom tunes arrive what is the actual process? Do I return to stock before taking my Gryphon out to update, unhook the OBDII, etc...? After updating I assume it is just the same as the initial installation. Can someone please advise?

yup, put to stock first and foremost, then load the tunes, then install like you did the first time you hooked it up! :)
