2010 King , Ness ac, 551 cams , V&H dresser duals, American Custom mid range baffles on reworked stock mufflers, power commander tuned by local tuner and don't understand the torque drop around 3k and the fuel consumption chart. When I hit the throttle I'm told it blows a little black smoke which means fuel isn't being burned , running too rich. I think the torque drop is why my buds bone stock 103 stays ahead of me through all gears by a bike length.
For you gurus : does this sheet look right or should I try another tuner?
Thanks in advance for any input.
Sorry I misspoke. The mufflers that were on the bike when it was Dynoed were the stock mufflers. I had American Custom rework the mufflers afterwards in an attempt to increase gas mileage. Guess I should go back and have it Dynoed again to see if it helped or hurt more. I didn't realize dresser duals were ng.

Blueline is with free-flowing mufflers. It sounded great but lacked torque. Redline shows a better exhaust match for my setup. Huge difference in performance.
Had same issue with little shorty 2 into 1 exhaust, but it looks cool and sounds awesome so I put a lollipop in it and could actually feel the difference in throttle response even before re-tuning.
