Blows it at full throttle which is normal but wof guy not so happy even though following the guidelines i cant see an issue. Its a 4m40t 2.8 diesel engine in a challenger. Apparently there is a air/fuel which can be adjusted to temporarily limit fuel. Im gonna put in some treatment as well however ...

Wanting to temporarily reduce black smoke output

Hey all,

I need to temporarily limit fuel supply to my Mitsi Challenger 96 2.8 diesel.

Can anyone point me in the direction on how to do this.
