    Please post your tune and config you're using.

    From what little I can see, your fueling is WAY off. This in and of itself will cause surging issues if it's that far out of whack, which would explain why a "fresh flash" would pull fine. LTFT hasn't had a chance to settle in and was zeroed out.
