This should answer a lot of your questions about EFI Live...

If you're wanting smoke, the PPE is generally a pretty clean running tuner. You might get a little puff before the turbo spools, but thats about it. It will be very good power that feels smooth, and shifts smooth though. And it typically returns very nice mileage as well.
My advice is if you're decent with computers, and understand fairly well how your truck operates then EFI could be a good investment for you. If you're not good with computers, or aren't very mechanically inclined, then I'd stick with a box tuner since EFI Live is fairly complex.
Let me know if I can help.

More or less yeah. You buy EFI Live from one of the site sponsors (vendors) here, or another tuner of your choice. Most tuners include 2 free tunes with the purchase. You can load those tunes and run them, and if you want to you can modify them and try different things, or even make your own tunes. Or if you would like you can buy single tunes from about any tuner that sells EFI Live. You can pretty much make it as simple or as complex as you want it. Some people never try to modify a tune or anything like that, others have been running their own tunes for years
