Exactly. There's a highly reputable custom build and tune shop with a dyno in my area many enthusiasts use. I've used them too for some mods. I was talking about tuning to them - they say they can tune any car, and I believe it - big local customer base of performance car owners use this place. Anyway, they told me they use the Predator for tuning Challengers on their dyno, so chances are if you had it professionally tuned, the shop would be using a Predator while your car is strapped to a dyno. Naturally, if you did that and had to take it in for a recall or something to a dealer, you'd want to save your custom tune and reinstall the stock one so it doesn't get overwritten. If you have your own Predator, you can pull off a custom tune and store it in case you ever need to swap tunes, etc. Then there's those added features of data logging, perimeter adjusts, and code clearing. Probably not something you'll use all the time, but nice to have when you need it.
