Did the Screamin' Eagle Pro Stage III Kit for Twin-Cooled 103 Engines. It's a brand new kit that just came out. Also went with new pipes and Reinhart Sleeves and a sweat Screamin' Eagle Air Cleaner. DynoJet was run before and after the mods. Here are the results:



Increased HP by 35.7 (74.41 to 110.11) and increased torque by 27 (93.78 to 120.78). Pretty happy with the results. Now I just have to wait until spring to ride!

 

Damn nice improvement. I can't find much info on the kit. What does it bump compression to?

 

Here's the kit - it's new so it doesn't show up anywhere but the new catalog...



Compression goes to 11.25:1

 

Thanks for the reply. What octane do you need to run in that thing now?! Mine was detonating slightly on 91 octane, so I run 93 all the time now.

 

I'm in the Chicago area and I always run 93. If it's less I add octane booster. The bike is put up for the winter at the dealer. This spring when the weather gets warmer, they'll fine tune it. It's a 2014 Ultra Limited. Once I add the heated seat it's essentially a CVO Limited for about $8K less.

It currently has 9,300 miles so I'm just around the corner from the 10,000 mile check up. I'm looking to go over 20K by the end of the 2015 riding season. Can't wait for spring!

 

Looked up the kit and found it bumps the compression to 11.25:1

 

Is this a street legal, warranty approved upgrade like the stage four kit is?

IMHO, we are starting to see performance upgrades that the water cooled exh. valve helps make possible. While maintaining reliability.

 

Was your bike Dyno tuned or was that a canned map in the super tuner? Very impressive, I think I want to do this myself

 

It's street legal. I've read that any of this type of work "voids the warranty". I discussed this with the dealer. It's where I bought the bike and where I had the kit installed. There comment was that they (the dealer) still honor the warranty since they did the work. If it would have been done by an independent shop, then not so much.

 

It was dyno tuned both before and after the work. I was surprised twice - first that the HP was so low originally, and then pleasantly surprised that it was so high after the upgrade. I was told it would come in between 100 and 103 HP. But then again, it's a brand new kit and the dealer was pleasantly surprised by the results as well.
