    Put it this way, you wouldn't want to be running 14.68 AFR while building boost on the foot brake.

    You wouldn't want to pop a cylinder in the beams or on the road somewhere. It will already be in PE if you are in boost so that AFR is what you'd want.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Check out this thread. As 5FDP stated if your in boost you should be in PE (or BE) if you have your tables setup correctly.

    Desired AFR is up to you, again as stated you don't want to be at stoich, but you can run it a little leaner or a bit richer to get the spool you want
