    Challenger RT Plus A5 392 Cam and BBK Shorty Headers - Propes tune

    Hello Guys,
    Doing my tune for 2 moths now. I have turned off ANN, and switched to VE.
    Recently finished my VE tabels adjustment, got nice 12.5 AFR during WOT.
    My problem is, that i should have a better times than 5,0-5,1s with 0-100kph.

    Can someone please help me with the clue, what could be done better?

    I've got a 2013 Challenger with 3.06 axle, A5 (NAG1) transmission, BBK shorty headers, Comp Cams .600" Lift Beehive Springs Kit, 392 Cam.

    I've read a lot of topics, even compare others tune (Diablo 93, etc.) but i can not find the answer.
    Should i go still with WOT Spark, or Exhaust Cam Angles, or Pedal follower, or maybe Transmission tuning?

    Please help, and thank you in advance for sharing your experience.

    Tune finalizes

    I got 12.7s quarter mile on public road.
    Feel free to use.
    Spark knock eliminated, NAG1 has been a little bit advanced.
    Good stuff.

    MDS, anf VVT still operatable.

    Have you tried it with your "sports" torque converter settings put back to stock. Does it make a difference?

    Maybe your tyres arent hooking correctly ? Basically your launch isn’t optimal , next step is a new lsd differential this will improve your 0-100 and better tyres of course

    I think i got best tires for daily drive - Michelin PS4S 275/40R20 rear.
    Problem is i cannot move any further. Messing with spark doesn't make any difference to be honest.
    Any suggestions Guys?
    Yes, thinking about converter.
