Does anybody have any results strickly with and without an idler pulley after a pulley swap? On an earlier post I had my dyno graph, I was getting my maximum torque at 3800 rpms. Is that normal? I just can't tell if I'm getting any belt slip so I would be interested to see if anybody has got their number before idler pulley and after! Thanks for your help! 475/490 seems low considering my mods, with lt's and all, but maybe that's right. I'd really appreciate other people with lt's to chime in with their dyno numbers
