I am having a kenne bell 2.2 put on my car in a couple weeks and have a few different pulley options to run. I am either running a 3" upper with a 2lb lower, or a 3.25" upper with a 4lb lower. Not sure if either setup would yield any difference, but I have read a lot of contradicting opinions on whether or not lower pulleys give more torque than boost from upper pulleys. Any input is much appreciated!
