Diesel Performance Tuning — Gold Coast & Tweed
Custom diesel tuning and ECU remapping for 4x4s, utes and trucks across the Gold Coast and Tweed. We write every tune to your vehicle and the way you actually use it — towing, touring, work or daily driving.
Diesel Performance Tuning done properly, the first time
A factory diesel tune is a compromise. It has to suit every fuel quality, every climate and every driver in every market the vehicle is sold into. That leaves real gains on the table. Our diesel tuning service replaces those factory compromises with a map built for your engine, your fuel and your right foot. We read the standard calibration, log how the engine behaves under load, then adjust fuelling, boost, timing and throttle mapping so the engine makes its power where you need it — down low, where towing and off-road work happen.

MORE ABOUT DIESEL TUNING
What a Custom Diesel Tune Actually Changes
Modern common rail diesels are controlled almost entirely by the ECU. Injection quantity, injection timing, rail pressure, boost target and throttle mapping are all software decisions, and all of them are set conservatively from the factory. When we tune your vehicle we adjust those tables together rather than simply adding fuel — that is the difference between a real tune and a plug-in power box.
The result most customers notice first is not peak power, it is drivability. The engine pulls cleanly from low revs, the transmission stops hunting between gears on hills, and the vehicle holds a gear when towing instead of kicking down every time the road tilts up. Peak power and torque go up too, typically in the range of 20 to 30 per cent depending on the engine and what supporting modifications are fitted.
Tuning for Towing, Touring and Work
A van behind the tow ball changes everything about how an engine is loaded. Towing tunes prioritise mid-range torque and cooler exhaust gas temperatures over headline numbers, so the vehicle sits comfortably at highway speed on long climbs without heat soaking. Touring tunes lean towards economy and smooth part-throttle response for big interstate kilometres.
Work vehicles and fleet utes get a different treatment again — we focus on throttle response around town, clean loaded take-offs and consistent fuel figures across a fleet. Tell us how the vehicle is used and we will build the map around that, rather than handing you a generic file.
Safety, Reliability and Warranty
Every tune we write is built around engine longevity. We monitor exhaust gas temperatures, boost pressure, rail pressure and air-fuel ratios throughout the process, and we will always tell you honestly when a vehicle needs supporting work — a better intercooler, a healthier turbo or a fresh service — before it should be tuned.
Our tuning is focused on performance, reliability, towing capability and fuel economy. If your vehicle is still under factory warranty, talk to us first and we will explain your options clearly.
"Great Service. Cleanest workshop I've ever seen. Mick was straight-up, no BS and really helped me sort out a long term idle hunting issue, adjusted the fuelling and now my 80series is running like a dream. I'm heading back in a few weeks for injectors and a fuel pump rebuild. Highly recommend."
— Mitchel Smith
"Mick and the team at Coastal Diesel were great to deal with. The service and installing King suspension on my Isuzu NPS truck was top notch."
— Sam Schoeller
"Was looking around for a solid while for someone to do a front swivel hub rebuild on my 80 Series Land Cruiser. Contacted a young fella named Riley and he managed to book it in for me with close to no notice and got it all done on a Thursday afternoon! Would 100% recommend Coastal Diesel Solutions to anyone in need of professional, talented, fair-priced repairs. 5 stars without a doubt! Solid work team 👏"
— Andrew Bower
"Had issues with my car going into limp mode. Been to multiple mechanics, no one could fix it. One of my mates said to go to Coastal Diesel and they didn't disappoint — they did a great job!"
— Radharaman Beresford
"Highly recommend. Fixed an ongoing problem with a power issue related to the turbo and fuel delivery. So much care in his work, very knowledgeable without the BS. I'll be trusting all future services and mechanical issues to Coastal Diesel Solutions."
— Janaka Peterson

"Highly recommended. Dropped everything to sort a fuel issue we had with our 4WD whilst we were on holidays 1100 km from home."
— Lindsay Wallace
"Coastal Diesel did a major service and fuel system recondition to my newly restored 75 Cruiser. It runs like a dream and safe to say after a week at Fraser Island she has been put to the test. Nice to see decent workmanship is still around. Thanks to Mick and the team, I know where I'll be spending my money. Cheers!"
— Frank Waite
"Couldn't ask for better help. Mick is a top mechanic with a great personality. Don't bother wasting your money elsewhere!"
— Aaron Fairfull
"My 2013 diesel had been sick for a long time and many non-diesel mechanics charged a lot but couldn't fix it. Mick returned my call on his Christmas holidays and made time to check my car was safe to drive until he could book it in. He's kind, honest, reliable and genuinely professional — sent photos, kept me informed, and definitely won't rip you off. Turned out to be a cracked hose and solidified soot in the pipes. Now she purrs along with no smell and dramatically better fuel economy. If you have a diesel, you need a diesel specialist — and Mick is THE diesel specialist."
— Donna Dibben
"These guys installed a new engine in my Ford Transit when no Ford dealership would help. I'm now ready to take it back for its 1000 km check-up and can't find anything to complain about. Well done boys."
— Norm Morrow
