Tuned 998 idle AFR?

[justinator]

Okay thanks.. Time for a fuel pressure test.. I'm idling pretty rich, guessing I might have a newer pump like justinator was posting about. I'm in the mid to upper 11's on a new motor..

Jon I just looked at some old data logs from last winter on my 2020 with td tunes and my idle afr was 11.6-11.8 on a warm motor. The idle I logged was over a minute and this is where it stayed.

Good to here! Mine is just under that.. Thinking im good.. Only thing I thought might be off otherwise she was good all the way to the BAR.. I beat my buddy on his Cat 6000 by 1.4 gallons at the station.. Of course we might have been cruising at times around 80-90? LOL that 600 was working to keep up. Had to set the rings !
