    06 Charger with surging on decel

    Reaching out for some help please. I have this charger I'm remote tuning. The car is running strong but I'm really struggle with the surging when it decels. Asking if you guys can take a look and let me know what I'm missing with this one. I'm not sure if it's cam relates so the cam card is also attached.

    Cars running a built 6.1, nothing over the top. Drop ins, stock injectors, long tubes, stock intake, stock throttle body, NAG1 with a 3200 stall.

    Try playing slightly with torque model / loss /friction base thats basically how much delay the tb has. make small changes on the small end of it and see if that helps.

    Looks better but it's still stalling on him. It's downshifting really late as he's coming to a stop and the RPM is dropping too low. I've adjusted the downshift to get it to downshift earlier to see if that helps him.

    whos cam is that???

    i LOVE THAT CAM CARD as it clearly instructs the installer to measure the lobe centerline

    see where it says "put the intake lobe at 4 degrees advanced" ???

    whos card is that and did you listen to the grinders instruction?

    I didn't do the build. not sure who built it but I was told it was a reputable engine builder. The cam is from Bullet Racing Cams. Nothing I've tuned before.

    Thanks @MadhousePerformance, it's improved the decel and holding RPM. Appreciate the help.

    What did you do to fix the surge? i have 2014 charger 5.7 cammed and supercharged and it have surging issue. currently remote tuned. it slightly surges while driving and surges alot when coming to a stop. rpm jumps like 200-300 rpm. it did have idle surge but its been fixed.
