its an adjustable shift kit, alls you do is change out from the 50ohm to the 100ohm depending on how harsh you want the biatch to shift, cost like $5 but is slightly confusing b/c theres two different storys on how to do it in the thread
i wish i could find it ive been looking for a bit know but it dont look like it exists anymore, time to talk to sig again.........maybe hell chime in
