“Far out its a different ute!!! completely unrecognisable performance.
We had a 6m triple axle trailer on the other day loaded with 170 bales of hay and it pulled like a dream.
The throttle response and torque seem to be on another level, it keeps pulling and gear selection out of a standing stand is awesome.
I’m really happy with it. I appreciate the work and thankyou Diesel Services- Matt Hoyes, Ararimu Baling- Ford Ranger
