    426 N/A Just when you think ya got it Idle surge out of no where

    Ok been a while since I had to revise the tune on my car but here we go.
    car ran great in Hawaii moved to North Carolina still ran good. now the car has only made short trips its whole life no more than 10 miles at a time. i now drive this beast 19 miles on the highway to work. The adaptives are what i believe is messing with me. (as i can reset them and the problem goes away until after my next highway trip.)
    it will surge going from D or R to P/N also when putting it into gear it throttles up and has to steadily come back down. so when going from R to D leaving a parking lot it gets all out of whack and surges all over the place until i reset the adaptives. Ive also noticed hot starting it cranks for a while before it lights like 2-3 seconds. in the log im posting it shows a bit of the surge from r-n and d-n not the crazy wild stuff when it really acts up. Hopefully some GURU's on here can help me out. Specs on the build are in the signature. Gettin ready to go standalone just to be rid of these adaptives. Please take a look guys let me know what you think or hopefully know. everything ive done to this tune has been learned from this forum and the tuning school material. its by far the largest cam ive tuned in a Gen 3 Hemi it runs like a bad ass puttin 618HP to the tires on Torco 110 all motor. just wish to get rid of these nasty idle surges. any help is appreciated guys.

    One thing to try is increasing the values in the GS Torque Reduction table.

    No dice it actually made it worse pulling throttle putting it into gear made it almost die going into drive then made the car lurch forward as it tried to stay running.
