Hi everyone, this is my first post.
Sorry if this question has already been asked…
I have a Power Vision 4, I would like to know what is the best mapping (then I will do autotune) for my bike (Harley Road King Special 107 – 2017) with:
- Arlen Ness Big Sucker Stage 1 air filter
- Screamin' Eagle Street Cannon Slip-on exhaust.
I flashed this one, 19T107a02303, I don't know if it's the right one, but I won't be able to try it for a few days.
Thanks!

Just curious, who provided you with that tune? Dynojet? It's probably not going to matter too much if you're going to autotune...plus the fact that you basically have a Stage one set up, autotune might be a bit over kill. However, that's your call.
Fuel Moto will send you an excellent tune for your bike. They will email it right to your Dynojet app. Those guys do more tunes on Harleys than anyone on the planet, and they have a huge library of tunes for every possible stage and setup. With one of their tunes, I wouldn't even bother with the autotune (it is expensive and not worth the money, especially for a stage one setup).
I swapped mufflers on my freewheeler and ran auto tune on my PV4 I ended up with a mess. Lost my gear numbers except I had a 4 when I was in fifth. Idled just above 800 rpm. Exceleration was terrible. Stopped auto tune and put it back to what Fuel Moto had sent me and it started running great. Get tunes from Fuel Moto is the best deal.
The PowerVision4 app proposes it by setting "Slip-On only" and "High-Airflow" as variables...
However it seems to work well
Ok, so it's a Dynojet provided generic tune. If you're happy with it, then all good. If not, give Fuel Moto a call, and ask them about a specific tune for your bike, and what they think about autotune for a stage one setup.

I have a 2021 Sport Glide with the 107 engine, slip-on muffler and air cleaner. The PV 4 map that Fuel Moto sent me when i bought the tuner from them is spot on with three auto tuning sessions. It picked up some power over the Screamin Eagle Bluetooth tuner that was on it.
