    no lift shift car is popping and drops rpm after and goes lean

    i have a 2015 s/p 6.4 6spd gen3 whipple 2.9L makes 18 to 19 lbs of boost running e90 fuel and seems like afr is still a little rich I have a n2mb wot box so I can no lift shift but it was not running smooth at the track every time I would shift it would pop and backfire I got a data log of it and this is the tune I was running
    seems like it just falls on its face like lose of ignition spark or something

    any help would be great
    thank you
