    Tune and file attached showing ecessive lean at tip in, with tons of knock.

    A certain unnamed person blamed (and still blames all of us) on the lean transition purely on un-tuned transitional fuel (SD tables)... but this log has SD tables 200% richer than my now "TUNED" SD tables, so If there was ANY truth to that I would think I would have had slightly rich transition fuel, or at least decent transitional fuel. According to that theory, now I will run ultra lean, grenade for sure.

    It's all starting to come to a head. I've been so in over my head with my damn truck lately that I haven't even been able to get Chris the log he requested.

    and the last thing you want to do is go run it lean again for the sake of a log...

    The lean spot is avoidable. To be honest, if you're engine is still on the warmup cycle and it goes lean for a bit and doesn't detonate, it's most likely going to forgive you.

    But right now trying to tune an E38 on SD is kind of a pain in the ass. See my Silverado has Kenne Bell supercharger on it with a vacuum bar setup for all the accessories. That means it boosts instantly. If you hit the throttle at idle, by 1,400 rpm it's already built 18 pounds of boost. And it required an additional 1,000% fuel on the base gain because it was going so lean on tip in. I feel your pain.
