I am trying to remove the rev limter in Park/ Neutral but it do not go above 4000rpm and then raise very slowly. I raised the neutral cutoff in the DFCO tap to 5800. I also disabled the Fuel cut torque ratio and spark cut torque ratio for "Engine speed limit" and "RPM guard" and no success. Is there anything else could be changed to rev the motor to higher rpm faster like the mustang?
