Finally Switched to "quiet baffles" from "performance baffles" with my Rinehart True Duals and what a difference!! More area under the torque curve is what I was looking for. 2200 - 4700 rpm over 100 ft/lbs of torque; I feel this is a great torque range for a heavy CVO bagger.

Numbers are lower, but different dyno, different conditions, different operator, and a new tune. He told me that his numbers run about 10% lower than other dynos when he does a comparison which proved out when he did a baseline run on my bike. The numbers were about 10% lower than my previous dyno graph showed. Anyway, here are the two dynos:

1st Dyno Chart is with "performance baffles" - 100 ft/lbs torque @ 3250 rpm

2nd Dyno Chart is with "quiet baffles" - 100 ft/lbs torque @ 2200 rpm
 (Tuned by Wayne @ Mile High Harley, Aurora Colorado).

The "seat of your pants dyno" difference is amazing. Now I have to get used to "short shifting".

I want to thank Steve from GMR for his suggestions regarding the baffle change.
