After searching around, it seems that @rabtech , @StickerDick & @iNewton have taken the plunge to go Haltech. I'm sure others have also.
While searching around I could not find a thread dedicated to replacing the stock ECU with a Haltech. There were lots of references to "Haltech" on the forum.
According to Haltech website they now make a custom harness that makes the connection much easier to the Slingshot. The Elite 1500 with wiring harness sells for right around $2000
It states it works with 2015/2106 slingshots. Will it also work with 2017 and newer or must a new harness be made?

It would be great if users that are running the Haltech could post there experiences here. I'm sure there are others that would be interested.
To kick it off maybe describe why you went with the Haltech?
What your setup (motor, turbo, supercharger) is?
Did you tune it yourself?
Do you think tune files can be shared for similar setups?
