    Bumping shift firmnes on the 8 speed

    Don't see ramp torque so I'm assuming oncoming clutch pressure would be a way to firm the sift, anyone know?

    Can you please elaborate on the torque management aspect? I'm commanding higher shifts and after it shifts to second torque management is coming in and closing the throttle and giving it back after a sec.

    35% before I could tell any difference on the "normal" oncoming pressure.
