View Full Version : Snub pulley and idlers will it affect the air/fuel ratio???

I was if adding a snub pulley and changing the idlers will change the air fuel ratio?? I did not have any belt slip before but I wanted the reassurance. I pulled off the stock idler pullies and they where poor shape as far the bearing where concerned.

Thank in advance for the help and info.

If by "snub pulley" you mean auxilary idler (beside snout to promote belt wrap), no it shouldn't.

definatly NO tune change, but we are assuming that you either used a chip,predator,or some other tuning device for the SC pulley when you first put it on right? but no extra tuning will be nessasary.

you know for peice of mind, these AEM widebands that RPMOUTLET sells are getting rather cheap, I paid $375 for mine when I got it but I think there a lot cheaper now, it takes a lot of worry off my mind being able to see actualy live whats going on with the A/F at any time
