Power Commander III one cylinder down

Anyone have experience with power commander III's? Just got one for my '03 road glide and when it's plugged in it only fires one cylinder...when I return to stock it fires right up after it clears out the unburnt fuel from not firing that cylinder...confused. Have tried multiple maps with same effect. Unplug the PCIII, runs right as rain.

I had a PC3-USB on a Softail I used to own, got the tuner as a Xmas gift. Of course I had to run right out to the garage thru the snow and install it. So bike week is coming and I go to load the bike in the trailer (no, I'm not riding 1000 miles in 17 degree weather) and it won't start, no spark. Disconnect the PC3 and runs fine.
So my 90 day warranty is gone and I chuck it in the trash.
Now other folks here have said that you can send it back for repair, I don't know but I was really pi$$ed that I never even got to ride my Softail with the PC3 on it. It's worth a phone call...

Sounds like the tuner is broke
