Isn't the beauty of using the TMAT or comparable management system that you do self-tunes that are pretty darn close. I remember reading a story in AIM about self-tuning the TTS. After that, they took it to a dyno and the dyno guy was able to get +1-2 hp. It was one of the Yuill (sp?) brothers. So, is it worth the dxtra cost for 1-2hp? Sounded like the TTS got it pretty darn close.

I might suggest map 548 ... for a 103 with Red Shift 575 ...
The other one I might try is map 398 ... for a 103 with Red Shift 577 ...
Think I could go either way with these two maps but think they'd probably be your best shot ....
Neither is a 100% match, but going with as many same or similar characteristics and then looking at the cam spec match to your S&S 570 ....
Pros and cons with map 548 ... map is for a 2-into-1 pipe and the build uses ported heads ....
map 398 ... Red Shift 577 I think is a slightly better match-up with the S&S 570 cam ... duration of int/exh are really close and lobe separation angle is like 103.8 for Red Shift and 103 for S&S ....
As I say, neither is perfect, but if you're running with the Auto Tune function, either one should get you dialed in above 97% in my estimation ....
My $0.02 for what its worth ... will be interested in what you end up doing, so please keep us posted ....

... if I get a few minutes, I may pull each of the maps up and compare their timing advance curves to see how close they are to each other ....

I'll use the 398 first, I think the probs most people have with TMAT are caused by cam selection and timing diffs between the selected cam and actual cam without timing adjustment.Will do the load today and get back to you all, thanks for the advice.
