its pretty easy to install, but not the easiest to use. it comes with a nice manual and there are a few write-ups online on how to set up all the options, and once you do its pretty nice.

anytime you raise the boost you need a retune

I've heard otherwise. How sure are you about this?

Or can you.. get tuned on 20psi, then turn it down to 14psi and be fine.. Turn it back up to 20psi, but never go above 20psi or you'll need a retune?

yes you can do that.

if you are tuned to a certain psi, you can go up to that and be fine. any higher and you are asking for trouble
