JMO based on what I have observed here over the years with Evolve.
They are great at getting really good product out and have done a lot of tunes (see GB section)

Where they fall down, IMO is when ever there is an issue they go silent.
Not that they are the only ones with issues, but they seem to turn a deaf ear. (many posts on this)
It took them ages to resolve the h&t tune issue with this mod, with several people left hanging.

Re the tune in your price, it is just that, it's built in.
They will sell ( or at least used to) box only & no tune.
But you may well be right, packaged may be less expensive. (but not free)

Personally, If I was doing this mod I would go the same route as Vanne.

Please note I'm not bashing Evolve, I have their Eventuri and think it's a great product.
I just see many issues posted and none, that I'm aware of, have been posted with the route Vanne took.
