One final thought on this, you may want to try adding more restrictive baffles or taking the baffles out, drilling the back or fronts and running a bolt through them. I read about this after I got rid of mine. It adds enough back pressure to solve the problem. I did not try it.
I think torque cones could possibly not work with the autotune and true duels issue. My reasoning is because the autotune will still feel the non-restrictive exhaust and calibrate wrong. The torque cones are installed at the heads correct?
2 years ago I had Rinehart true duals, SE A/C and T-Max on my '07 Ultra. My bike pinged under load at highway speeds. Switching to a V&H Propipe cured most of it, removing 2 degrees of timing fixed the rest. Bike runs strong.
Thanks to all who responded. Not sure what I am going to do just yet. Lost my good job a year and a half ago. took a 60% cut so I really have to watch what I spend. I may look into cams.
The thundermax is a pretty good unit, but it won't tune itself to your bike. It will, however, adjust the fuel. You still need a good dyno tune to get it right, or you'll have a slow bike that pings.
+1 on the last post I have a thundermax on my nighttrain no auto tune but tuned by a builder. He had 2 play with the timming a little bike makes 101 hp 103 tq with motor work and the thundermax

You might try and just do the running a bolt through the baffle trick to add some back pressure. Total cost about 2.00. You may also go into your map and retard the timing a little but that will cost performance.
A lot of the recommendations that you're getting are work-arounds...not fixes. To fix the problem, get a SERT and a DYNO.
SERT Did not work in my bike, it's how I ended up getting the Zippers ThunderMax. The dealer could not get my bike tuned. Of course the 07s were new back then so the Dyno guys may know what works now but none of this stuff is work arounds, It's solving the problem in various ways.
