I just put an andrews 57h in my bike. I'm running 4 in rhinehart true duals and a heavy breather. My dyno numbers are in my sig. All I can say is you will have more then enough power. My bike runs like a bat out of hell. It will litterally take you out of the seat.
All your power is gonna be at 2000 to 4000 rpm. This is normally where your bike is running at speed. Andrews actually makes the se cams for harley. I would suggest an andrews myself .

timimg
I don't know how anybody can run any of the maps that I have looked at, stage1 or 2 or 3. They are all advanced way, way more than my bike will handle. I've had to drop timing from 2750 to 4500, 70 & 80 kpa 12 degrees and lesser amounts in other areas to keep it from sounding like shaking a coffee can full of nickels. This thing has always pinged, and no increase in fuel would stop it. The only thing that worked was to drop the timing. It's not the quality of gas either, unless all the 91 octane is crappy in Colorado. It took all summer two years back to get the timing right. I was starting to think it came from the factory with 12 : 1 pistons. I had to copy my stage 1 timing chart to the new file that I used after installing the Andrews 57. None of the files that people sent me would work right so I started with a new file that had the same base number as the files that were sent. My recordings now show 2 or 3, 2 degree KR events on a full recording, and there were no audible pings.

You should be able to tune the pinging out. My 96 was the same way. Man that engine wanted to ping. I actually never really solved it until I started working with Fuel Moto. Jamie and Co with some effort got me a map that worked. Once I went to the 103 the motor tuned as I expected it to. I was able to time the knock events out pretty quick.

I'm using the SEPST. I can get the knock out now that I know how, but when I mentioned it on here two years ago everyone insisted that it was because it was too lean and that was definitely not the case. The AC and the Pro Pipe did make it lean but that was pretty easy to figure out and remedy. But the timing charts on the base files are screwy. There were places where the front would go up and the rear would go down or visa versa on two adjacent cells then a cell or two away from that area it would do the exact opposite. Like somebody pulled the numbers out of their ***. The stage 1 file had more aggressive numbers than the stage two or three. I'm sure that there are a lot of bikes that would show KR events if someone took the time to record and look.

What's with "audible" tuning? Only data should be used, not an audible sound, right?

91 is about as good as it gets around here. The pinging was audible, thats what got me looking at the KR events in the first place. I was getting a lot of 4 and 5 degree KR's both front and back and it was audible but after going through this two years ago I knew what to do so now I may get a 1 or 2 brief 1.5 or 2 degree hits on a long recording, if they didn't show up in the data you'd never suspect that they were there.

Stage 1 map will have the timing values way too high.
IMO, a base map that used 259E cams would have been a place to start.

After looking at the base files again I think the one for the 204 cam (044sdh-- may be a better choice to start out with than the 259E. The timing and duration are closer to the 57H with the main difference in lift. But all of the files seem to employ rectal numerology and both have ACR turned off. Wish I could get my hands on a dyno. I don't know if any of the dyno tuners in the area really understand all this, they seem to just plug in a canned map and call it good.
