Those come with a 5.9 ECU, so needs a PCIII or the like, or reflash to alter fuelling.
It's been a while since I rode one, but I recall they ran decent stock.
Trim is adjustable, and no wonky air idle valve.
The last one I rode had big-bore hi-comps (1079cc), light flywheel and BST's on it.
It was pretty snappy.
I forget what Steve uses, but he can tune without a piggy back. Yep, open loop 1000 DS is much less wonky than the closed loop variety.
