Okay I have the good pulley puuler after buying one of those junks. I have everything for the job of installing a 2.80 but is it a two man job every picture I have seen there is two people? One more thing I got a Apten chip tuned to my cars code will I need to send the chip back after I install the 2.80 pulley? Or will there tune do okay with just a 2.80 pulley?
