I had the 103 stage II installed last fall, with the down load the bike ran ok but had a stumble around 2200 rpm tried a few things but just wasn't right so I had it put on the dyno. As for how much or % of gain I couldn't tell you. What I can say is I love it,
I have a 09 Ultra Tq comes on right were I want it mpg is 42-49 depending on who I ride with and my right wrist. would I do it over again you bet.

I have the 103" Stage II with 255 cams. I originally had the factory download and then went for a PCV with Fuelmoto's mapping. The bike ran fine except for some pinging. I took it in for a dyno tune to get rid of the pinging and what a surprise! It came out running like a different bike. I could feel it in the first mile. Way more responsive and even feels stronger. I'm convinced that a good tune can make all the difference. BTW, the 103" with 255 cams is a very noticeable improvement in power over the stock 96". Well worthwhile.
