Paul Wright, Top Soil and Sand, Horotiu, with his Volvo truck

"My truck has over 1 Million Kms and has been plagued with an ECU fault relating to the AdBlue/SCR system. I have been battling constant engine de-rating issues and have spent countless amounts of money with 2 other companies trying to sort the issue. 

I got in contact with Diesel Tune NZ through a friend of mine and they were keen to have a look and see if they could help. Diesel Tune NZ had the truck for a couple of hours and I haven’t had a single fault or de-rate since. I can recommend Diesel Tune NZ for all your AdBlue/SCR related faults."

Paul, Top Soil and Sand, Horotiu

"Just got the Hilux back from Craig at Diesel Tune NZ, can't get over the difference it’s made in the torque and HP, completely changed the vehicle. Craig went above and beyond in his way of service, couldn’t recommend enough to anyone with a vehicle that’s just in need of a wee bit more puff. Cheers mate she’s a weapon now"

Tom, Christchurch

Toyota Hilux tune to increase torque and horsepower
Dave's new Holden Colorado after receiving a custom ECU remap from Diesel Tune NZ

"Very happy with the job done by Diesel Tune on my new Holden Colorado. A very noticeable difference towing the boat up over the hill to Akaroa. And even uses a bit less fuel all round, definitely a win-win in my eyes."

Dave, Christchurch

"I recently had my Land Cruiser tuned by Craig from Diesel Tune. Service was fast and friendly, the end result is amazing. It has turned my Cruiser into an entirely different vehicle to drive and to tow with. The acceleration and torque is incredible. The best money I have spent for some time – thoroughly recommend Craig and DTNZ."

Pete, Blenheim
