Terry, can you briefly explain the auto tune? Does the JB4 "auto tune" take into account altitude and octane? I have never quite gotten mine where I want it up here in CO after multiple log runs.
I guess what I'm asking if, in my case, map3 is not enough power and map 5 is sometimes too much (occasional timing pulls and surging) will auto tune mode put me somewhere in the middle? Looking forward to the JB4! I'm hoping it'll be my fix!
