We have a 2006 5.7 that we put a comp 112-502-11 (intake .547, exhaust .550, 114 separation) 2014 5.7 heads and intake. It is showing lean at idle but during pulls it is fine. Im hoping someone can help out. Thanks

Post logs and tune. Could be a number of things.

I sadly dont have them, we are not doing the tuning but the tuner it was at said he commanded for more fuel at idle and it wasn't doing anything. I know not having the logs and tune avaible makes it very hard to help us.
