Your best bet would be to try and call nmotion and see if they have any reccomendations. if not then try a nice starting point like Dobeck recomends and tune it in yourself. The dobeck is pretty easy to dial in nicely.
i bought the nmotion from the site sponsors here. i found when compairing the actual bends and product overall against the ron woods it lacked in quality. bends were not consistant pipe shrank up in some areas. the welds were not ground down and it was not ceramicoated on headers. with the contours in the bends being as dramatic as they were i figured i would loose hp from that and by looking at the woods pipe, i decided to go with that 1. hp #'s not sure on the nmotion but i am real happy with my woods.
