Agoober I wonder why your tune has such different parameters than mine? I mean the curves are similar but yours developed a lot more torque less some horsepower than mine did and I have a good for torque 2-1. But I am stoked with how it pulls across the rpm range and the power for only a compliant stage 3. Next jump to say a basic 128 & supporting components costs a lot for another 25 HP. Think I'm good for another 2 seasons anyway.

It's not mine Vern just a stage 3 as there was not many graphs of them.
Yours looks a bit rich to 3k too,other than it looks good. Different dynos different days,could be the exhaust, riding is what matters and yours looks like a fun scoot.

My understanding is that the SE-PST is more limited with maps and or fueling adjustments than aftermarket non EPA compliant tuners especially below 3,500. He had to use a base map from a 117 to get enough fuel but in doing so it makes it a little rich down low. I believe H-D shows about 108 HP for stage 3. I'm assuming the extreme AC S&S header & pipe must be flowing some air to make 116. I did also upgrade the TB & got rid of the stock plastic intake. Think down the road a non MoCo cam de-cat & PV tune could pick up much?

The bike should clean itself up down low I believe over time, but I could be wrong. What TB are you running the SE55 or the SE64 ?

I've seen a few graphs where the 64mm TB was not as good till about 4k or 4500 then they take over with more all round up in the rev range.

A longer stroke 117 might pull a little more air down low? I can't tell it to ride it even down at 2k. Just read where Jamie at Fuel Moto said the stock injectors do good into the high teens for HP. So apparently I'm getting close their also. The air fuel ratio on the chart shows a skipper light above 6k also.

Here are two builds we did this week on 2020 Road Glide Limited's from Texas, we did identical engine combinations consisting of the FM 128" kit @ 11.0:1, FM Level A heads, Wood WM8-408 cam, SE 64mm TB w/Ward CNC manifold, AIM SDR clutch, Dynojet Power Vision, one bike got a Jackpot XXX headpipe & Outlaw mufflers, the other a D&D Billet Cat 2/1. One bike was equipped with RDRS.
