    Tun refinement help

    Hi everyone!


    So as the title says need some help really quick with values. I got my tune to Crackle/Pop. But on Downshift its more of a Crackle/Burble instead of a Crackle/Pop. When i rev in park/N with no rev limiter in place it pops like gun shots. But when i down shift it does not.

    My values in both menus for my octane have been tuned via data logging and currently setting at -15 (tried -22 but ran way to rich) -10 wasnt loud enough and -15 is a good middle ground so far. i wonder if i push it to -17 will it make it pop on down shift?

    or is it because i still have my Displacement on demand on? aka AFM.

    any help would be great.
