There are other options available, some very much cheaper.
You should do yourself a favor and search up on the topic before making a tune decision.
There are also some in the pipes both piggyback and flash.
I'm waiting for my VAC module (they're sending me one for evaluation), but as far as I know, nothing's changed.
I've heard from 2 different people that have the module that there's no high end grunt, but I can't speak from personal experience, but with 2 other tunes tested on my car, I'll have a pretty good point of reference when it arrives.
