    If your car is stock I think you'll likely find that GM's airflow models are pretty good. On the car I was dealing with I don't think spending the time to tune VVE would have made any improvements...

    I didn't look super close through your tune, but I think its unlikely any Stage 2 sized cam is going to be happy idling at 550 rpm or less.

    Just to rule something out, log your EVAP Purge. I stumbled on it by accident, wondering why the fuel trims at idle in my 18 Silverado would swing significantly. Some times trims would be as you...

    This is as much of a question as it is observation from me as where I live we don't have E85, so I have zero experience with it. But, 33 deg at WOT seems like a LOT of timing. I'd have thought even...

    I was watching a video the other night in which it was stated that the L83 gets really tight for piston to valve clearance once you get into the 220 deg duration range.

    As an experiment, richen it back up some.

    If you're actual air/fuel ratios are in the ballpark of what you're commanding, my experience with LS & now with these LT truck engines is that they...

    I can't say if its related to your problem or not, but have you tried putting the OE MAF curve back in it? The one in the tune provided is wildly different & not very "curve'ish".

    Just for clarity, did you have Track Addict running at the track when you made your 12.68 pass, or is this comparing your track time vs what you recorded with Track Addict on the street?
