Indeed Carlos3621. I had the Stage 1 completed previously and at that time had the SE Tuner. So this Screamin Eagle Stage 3 utilitzed all Screamin Eagle. I wanted to keep it with factory warranty for the new M8 and see what the HD packages would provide.

I am pretty satisfied!

I certainly did not pull that out of my ***...I looked it up. I have not noticed if most utilize the SAE correction method vs STD. Is that the standard that is to be used? I will certainly ask for a copy in an SAE method if they can print it in that version.
No issue with using STD dynos IMO. Its just that it really can't be compared to other dyno charts. Using SAE charts compensates for air temp, humidity, altitude and other basic parameters that effect the engine performance so its easier to compare to other bike dyno runs, even your own in the future. If the shop has the STD dyno run for your bike, they also have the same chart in SAE in their database. Just ask for a print out in SAE.

Very nice Chart for a 107 with Cat, easily working what the 110's were with stage II. Hope you enjoy, ride safe and fast.

FYI, 115 on STD would be 114 or 113 on SAE

thats still not enough of a difference to really matter, but good to know.
this is still within the realm of what Harley claims on their SE stage 3 kit.
im sold! And actually in the process of getting this exact setup installed on my '17 RGS.

thanks for the info,
ride on!

We use both correction factors.
If it was dynoed before mods with STD, we do the "after" mods dyno test the same correction If the mods gain 30 hp....the bike will still gain 30 hp with either correction factor
For instance, 85 before with STD and 84 with SAE, the after 30 hp gain would show same percentage of gains.

SAE is preferred be you can compare one bike to another, on different days, and different weather conditions. It is more useful when comparing bike to bike.

STD is fine for a base line, then to run again for the changes made to the bike.

I always insist on my runs being done SAE correction factor 5 as that is the most useful for comparing

OP if you go back to get the sheet in SAE ask them to print it with the AFR graph on the bottom of it.

I am pretty sure the smile on my face has been frozen in on my ride back to the office with my bike. Even as they rolled it out, it sounded better. I was told the Service Tech was able to squeeze a lot out of the tune as they were getting more dialed in on the M8's and the parameters of the tuning.

Of course, I will say it does not sound like a Harley Pre 2017 with this big of a build....but is does sound good


Stage III - 2017 FLHXS - Yeah Baby!
The increase in compression no doubt wakes those pipes up a bit.
