Send out the PCM to be reworked?

If it was me, I would look at swapping axle ratio to a 4.10. Then take it to a dyno shop and have it tuned by a professional. Probably that alone, with no axle ration swap, would get you what you are after. No offense to your diablo its a great product, but its a canned tune. Cookie cuter one fits all. Not all trucks are the same.
I've used both hand held tuners and custom tuned PCM. I prefer what has been done to my trucks with HP tuners.
