Well, I installed the 4 lb pulley today from JDM. Removed the PSP 2 lb pulley which was great. JDMs uses the original bracket and pulley mount. No problems until I went to put on the belt. It was tight before but I couldn't get it over the top pulley. Called JDM. Chip off the lower tit on the back of the idler pulley. This give additional room to push it down and with HELP you can get the belt started on the top pulley. They take an openend box wrench that fits the bolt on front of the top pulley and turn the pulley until the belt goes completely on. Wow! Two was great but four is even better. Stock boost gauge goes wayyyyyy over into the black. Truck is noticeably faster and even better at highway speeds when you wot it. No changes have been made to my chip yet and there is no detination at high rpm just before shift which I listened for. Truck runs great! Thanks JDM!!!!!!! and whoever answered the phone when I called thanks for the idler tip.
