I think both the TOR and the Trident use the TOR tune just fine. I don't know what IXIL is, did I miss a post for a new exhaust for the 1050 sprints?
Also, with exchange rates and shipping, the Trident looks to be closer to $900 or so.. But the vids/sounds/pics look like it is worth it..

The Trident has to be purchased from Wolf racing in the UK, but several US board members here have bought one with no issues.
If you have access to a dyno and someone who knows tuning, a tuneboy would be the way to go to really get a custom map, but if not, the TOR map is a much better "plug and play" solution (as far as I've gathered from reading here).
