The gains don't justify the cost. The only reason I see for a tune is to remove the CEL. I'm strictly speaking about the Trifecta tune. I've never tried the IPF but might if I have nothing else to spend on.
If I had to do it all over again, I'd do as much bolt-ons as possible, then headers, and then tune if you need the CEL gone. If not, I wouldn't even tune at all. I'd just spend the money on something else.
