Custom Dyno Tuning

More Than Just Diesel Performance.

Unprecedented torque delivery over standard.

Smooth power curve for all-round driving.

Better fuel economy. Safely & reliably.


Benefits of a CUSTOM DYNO TUNE by Ultimate Diesel Tuning.

  • Approx. 25-35% more peak torque and power. In some cases a lot more.
  • Reduced turbo lag.
  • Responsive throttle pedal. 
  • No more EGR related issues.*
  • Reduction in fuel usage by 5-10%*
  • Better & safer results than any generic & untunable “chip” on the market

Your turbo diesel vehicle will feel a LOT better in terms of
power & torque output, acceleration, smoothness & driveability!

*Ultimate Diesel Tuning guarantees no more EGR related issues as in no more clogged inlet manifold, provided that a catch can is also fitted. Fuel economy is dependent on how the owner drives it – the heavier you are on the accelerator pedal; the more fuel it will use. however, after one of our custom dyno tunes, you will use less pedal pressure to achieve the same acceleration as before.

Frequently asked

What is a custom dyno tune?

A custom dyno tune is the process of modifying the standard files & software within the car’s engine computer (called an “ECU”) to enhance & optimise the engine. This is to provide more torque, more power, more response, better driveability & better fuel economy for the vehicle. There are no replacement parts required & this procedure is carried out here, in-house, at Ultimate Diesel Tuning by our experienced engine tuners/engineers by utilising the vehicle’s factory OEM engine computer & our in-house machine, called a dynamometer (referred to as a “DYNO” – see below).

What is a dyno?

A dyno is a device/machine for measuring force, moment of force (torque), or power, plus other engine vitals. A vehicle is driven onto the dyno via ramps & strapped down. It is then driven on the dyno, allowing us to replicate road driving conditions at different speeds, RPMs, elevations & loads. The dyno’s computer will then record all the vitals such as power & torque, plus other important engine readings like air & fuel mixtures & turbo boost pressure, as the vehicle is run on the dyno. It is a very important piece to the puzzle when it comes to tuning a vehicle properly.


The Ultimate Diesel Tuning DIFFERENCE.

Here at UDT, not only do we have several years of combined diesel custom dyno tuning & mechanical experience, but we have also invested hundreds of thousands of dollars into required master tuning specialised equipment & staff training to achieve the best result possible for our customers.

At all of our performance centres, we have new in-house Dyno Dynamics dynamometers (that cater for both 4WD & 2WD vehicles) & all tunes performed are custom to each vehicle (not a generic flashtune), carried out to not only ensure a great increase in power, torque & response; but also to ensure that the tune is safe & reliable as well. This means that your vehicle will be 100% custom dyno tuned PROPERLY & individually by our experienced tuners/engineers using our master equipment & our in-house dynos – we will also perform the custom dyno tune to YOUR requirements & goals, also with your engine condition/age in mind.

A custom dyno tune by UDT is 100% NOT a just a generic tune from another vehicle that’s loaded into your ECU, with a provided “before” & “after” dyno sheet (which is unfortunately very common in this industry to do). We will ensure that you receive the best possible performance result, safely & reliably. We will totally transform your vehicle’s performance to the extent that if its ECU is put back to standard, you will notice the difference immediately – it will feel terrible to drive to you, it will be sluggish & you will feel that it’s very low on power! It is our experience & our attention to detail & care that we believe sets us apart from other workshops & tuners.
