    Developed a flare from 3rd to 4th shift

    What should I look for?

    1st to 2nd snap

    2nd to 3rd snap

    3rd to 4th like an inhale then exhale into 4th

    Tried changing shift schedule, verter lockup stuff

    Did you ever figure this out, I'm getting a flare up as well in the 3-4 on my hellcat. I'm runing a 2.7 pulley currently. I've have found that putting the car in Sport mode for transmission to affect the shift strategy has helped but other than that still at a loss.
    Hellcat PB > ET: 10.092, MPH: 135.650, 60': 1.492, R/T: .000
    Bone Stock Scat Pack PB > ET: 11.612, MPH: 119.52, 60': 1.634, R/T: .000 (gone but not forgotten).

    No. POPPed #7 ring land before I could get valve body out and inspect. Cars down waiting to get into a friends shop.

    I have a 5 spd NAG1. Don't you have the 8 spd?
