Is this too lean of an A/F at idle?

[QUOTE="S/CCobra03, post: 2618667, member: 22259"] I just installed a set of LT headers on my 03 a few weeks ago. I've noticed that the car is now idling at 15.2-16:1. It would always idle around 14.7 before the LT's. The WOT A/F has not changed. So will I have to get a new tune in order to fix my lean condition at idle? I thought custom tuning would only change the A/F under WOT. [/QUOTE]
