[QUOTE="04OWwhipple, post: 16238979, member: 178956"] I was just curious on what idle AFR everyone's different setups are running at and are happily idling smoothly at? Dialing in my Haltech Elite and my engine seems to be happiest at around 13.5-13.6 AFR. If i lean it out a little and target 14.0-14.2 I start to have little misfires and pops through the exhaust which lead to a slightly unstable idle. Setup is in sig but it is basically stock long block aside from going to 9.2-9.3:1 compression over the stock 8.5. Still on stock cams with unported heads [/QUOTE]
