Hey Dan,
I've got a Data Logit for the PowerFC. So if you find a powerfc map you need loaded I can probably assist there, but otherwise not the person when it comes to tuning.
If your running a Gen III PowerFC, I've got a reasonable map you can use, but just reduce the ignition timing across the map by 3-5 degree's and I reckon you'd be pretty safe. If your running a Gen II, I have no idea how much the map needs to be amended across map.
