Where did you get the tune from? If you took a tune from a smaller displacement LS and increased the engine size and cylinder volume that will scale up the VE values, maybe that's the problem. Looking at the log it looks like you can keep it going after the start with the throttle but it dies when you let off. I'd say its too rich. Your wide band should indicate this, are you logging it.
