so what is the general opinion on this? i have searched some old threads and it seems some say yes and some say no. is a re-tune needed if you run the 92mm pulley? in regard to the belt supposedly there is a 2mm difference in length, doesn't seem like its necessary if that is the case. iirc the pulley only adds another 1 or 2 lbs of boost, doesn't seem like a drastic change needing a re-map but i could be real wrong.
