If someone could help with this that would be awesome.
2008 5.7 Hemi Truck, Cammed, Headers, Ported all, Centrifugal Supercharger setup for 6-7psi at 6200 rpm.
The issue I can't figure out is that in the last rpm VE cell during WOT its going lean. Even with the VE value maxed out it jumps lean. Talking from ~11.5 to 12.5+ AFR suddenly. I have verified fuel pump supply is more than adequate. You can watch the injector duty working its way up to 65-75% until about 6100rpm, then it stops climbing or drops a little and AFR goes lean. It has to be a max limit or some setting I'm missing.
