Hilly13 advised finding a HD map with an intake open similar to what cam I buy. So what I got from you was I can use an SE204 map if I decide to go with 570's.

Jim the bikes go better dialled in, I've tuned bikes that are stock or just mufflers that put a smile on the owners faces, right cams are just a bigger grin factor, you just got to start somewhere and go through the process, providing the bike is in a tunable mechanical state it will all come together and make you a happy man.

 

No, I got it. I've asked S&S which cams are close to Harley grinds so I can use an HD map for a baseline. As 60gunner mentioned, he used the map for SE204's as a base map for his 570's but they come on too late for my style.

 

You can also degree the cams in, and get +2/ -2 and +4/ -4 degree gears which will move the powerband up or down a little on a given cam.

 

What about a 475 instead of a 570? I have the 475 from S&S that came with the pre-mapped PV-3. The canned map tune is decent but there's room for improvement IMO. I also have a SEPST. You think there's any chance of loading anything from the SEPST that I could actually use to tune it with the 475 installed?
