Ok someone explain why the C@L factory replacement works and a flanged 95mm pro-m is a bad idea. Always liked the Pro-M stuff better than the C@L on the 5.0 stuff. What kinda tunning issues will i run into if any? Has anyone personally tried one? With stock or 2.8 pulley combos. Funny thing is DeMolet is selling a kit with one for $490. If this doesn't work why are they doing this? Will probably use a predator for tune anyway.
