Greetings...... Finishing up adding a Whipple to an L83 2018 Sierra. I went ahead and upgraded to an LT4 pump and injectors. Can someone direct me on the changes to make to the tune for the LT4 upgrades? I just need a basis so I can get to the tuner 10 or so miles away. I figure I can lock the bypass open so I won't hit boost on the way there.
Thanks
