so back to this for a sec. Why would Triumph retard the timing on the TOR tune, I mean we are only talking a better flowing pipe (the TOR tune does not even account for a high flow filter) I did finally figure out the tuneecu comparative feature and it seems the only things changed are up in the 3k to 6k rpm range and indeed the timing has been changed (retard) some a fair bit, say 10 degree's.
