I don't like the blue smoke on an engine that new at all. Running too rich, you'd get black smoke not blue. I had a truck once that did that at 100K, and I traded it in right away.
I can't see how a custom tune would cause oil blow-by at all. I'd restore it to level 0 and take it to Ford right away.
