Pe Afr i'm tweeking the tune on my '04 GTO (LS1) and was wondering if everybody sets their WOT PE to ~12.5 AFR across the board or does anybody vary their AFR with their RPM?

Thanks for your reply. ok, so my peak torque is 4,800 RPM that I would set to 12.2-12.3 AFR then transition to 12.7-12.8 and back to 12.5 at 6,200 RPM. What do you set it for from 2,000 RPM to peak torque?
