Can't help with sm6 because I don't have. I've got the sm5 which is higher revved than the sm6 and don't have that issue. Sm6 is lower revved seems it would be a less likely issue. Ther has got to be someone else out there with a sm6 that can share their experience. Hard to believe rolling off the throttle and rpm increases:yikes:. But u would know your driving:banghead:
