Diesel Tune’s Craig Jones comes from a strong farming background on Canterbury’s Banks Peninsula. With a passion for all thing’s machinery and heavy diesel & engineering, his experience is an impressive CV of reputable NZ and European agricultural companies over the past 10 years. Along with the mechanical aspect of Craig’s work, he’s always had an interest in the electronics side of modern machines.  This is what has led Craig into building Diesel Tune NZ; a tuning company that offers clients a customised solution to their diesel engine requirements.
