What do you want done? Any dealer can put the latest BRP program in and monkey with the timing plus 3 to minus 3 degrees. (The latest program IS recommended for all XP's as it desensitizes the knock sensor and adds the ability to clear codes by shutting off the sled and restarting) For custom programming I believe the race dept does it, but you need a "spec" for them to do it. EI: RKT has their own spec.
