Guys, you don't have to do the relearn on these trucks. I thought you did too, but I never got a CEL and the Tech2 at my mechanics would not initiate the process, stating that the values were already good. The black box mail order tunes are just plug n play, even with a new PCM.
He can just order a tune via mail and plug it in, good to go.
EDIT - Whoops, didn't see that he had a 98. Going to have to do a Passlock/security relearn with a Tech2 for sure. So glad I didn't have to do that on my 97...
