2014 Street Glide Special @680 miles - D&D Fat Cat with moderate baffle, Heavy Breather and H-D Pro Tuner. Thought the numbers might be a little higher but dealer said their dyno does tend to be a little conservative and they might have said this was their 1st air cooled 2014 done. If I misunderstood that, I know they definitely said this was their 1st 2014 with a D & D done.

Indeed! I suspect we need to give the tuning shops a while to perfect their skills with them. If the factory can use higher CR and better cams as stock, we can probably look forward to a decent boost from our experts.

I can't see the torque line on that sheet. Have any with both? Have any with the base line? Surely they did a base line at 100% stock and then we could see the differences.
HP curve looks pretty good, and it is the curve that counts, now lets see the torque.

I'm seeing 2 lines on the chart that cross at about 5300rpms. I just assumed one was the horsepower line and the other was the torque line. That chart is all I have.

The two curves cross at just about 5,250rpm for every engine! The torque curve is the upper one to the left, the power curve being the highest on the right, hence 84HP/103TQ.

So are you able to see the line that wurk_truk says he can't see?
