Yea they take care of the tuning forsure! But jarrod at blackbear told me id hace to do a crank relearn after i got the new motor in and put the new pcm in! If i kept the 5.3 tune id be fine, but new motor and new tune, got to do the crank relearn!Crank relearn ? Why would you need to do that? Just trying to learn myself. Wouldn't the black bear tune take care of all the tuning issues?
