Hey Rich- I bought mine off of Mike Tolle at MT racing and your right I did not ask for a super low-end sacrifice all my top-end on the torque mode I went more middle punch and they are noticeable changes, but if I went the all low-end route he could give it to me. The mods I have done to my bike and the way I ride it all low-end would not suit me. Rich is right if you call Mike and tell him what you want he can help he has all different curves and he's cheaper than Tom Morgan and Mike is the U.S. distributor.
