I would guess to say since you changed the gears, Torque calculated is not matching torque programmed. You may need to adjust the torque and inverse tables.

You absolutely do not need to adjust TQ and Tq inverse tables when swapping to a different final drive ratio

Should be able to go into vcm scanner and input new gear ratio and update it
