cam is probably gonna want a little less fuel at idle, so plan on it being a little rich, and probably a little more at WOT upper rpms, so plan on adding some. So 20 is a good round number between the two.

Take a look at this post:

Most of the pics don't work anymore, due to changes to photobucket, but the info is good. I'm starting to tune my LQ4 swapped into a 1971 GMC Jimmy. I've running headers, CNC'd heads, 4" Intake, 3200 Yank, 223/231 .63x/.61x cam, Corvette LS2 Injectors, 4L65e. I've been using the info in that first thread, and have the truck idling pretty well now, and drives pretty well. I need to get my wideband wired in and start on part throttle next.
