Larry, Mike's numbers sounds close to where ours was at. I'll do a search and edit this post with that info soon as I find it.
Larry, below is a copy/paste of the text from that other post:

Weight probably has a lot to do with it. Our 3295RK weiged 13,980 at last weighing (admittedly quite awhile back). I moved from boost 2 to boost 3 because I figured in an emergency stop I want as much initial stopping power as possible. 2 is probably fine for most rigs.
For a year or so I ran ours on 7. When I had the brakes checked by our selling dealer he told me I had the brakes cranked down too tight. The linings were only half worn after about 20,000 miles but the magnets were nearly worn off at a 45 degree angle and the linings had some heat stress cracks. I backed off to 6.0 but didn't think it stopped as well as I'd like so moved it slowly up to about 6.3 or 6.5. I've forgotten now exactly what the setting was and no longer have the Prodigy to check the setting. On the current truck's integrated controller (essentially a Prodigy from what I understand) I have it set at 7.5. Hopefully I'm not stressing the trailer brakes but the controller uses the computer to match trailer braking to truck braking so I think we're ok.

That post is in the thread the following link takes you to. There's several replies listing how others set their Prodigy.
