Performance Chips

While there are many “performance chips” out on the market that has similar “expected results” The benefit of a Power Curve Performance Diesel ECU Tune over a diesel performance rail chip is vast.  You can see the difference in the corresponding dyno sheet.  The 79 Series Landcruiser was booked for an ECU tune and Diesel Performance Rail Chip removal.  The results were documented for the customer.

  • High-performance gains in the rpm the vehicle is used to tow, overtake and drive.
  • Aggressive power and torque in the rpm range the vehicle is driving and towing.
  • No interruptions from wiring and water faults to the performance chip.
  • Custom tuned to the vehicle, engine and drivers wish
  • Price at $1490 its more than competitive with every quality performance chip on the market.


A little explanation of the dyno sheet    

Left axis is power, the right axis is Torque, bottom axis is RPM Red solid line is factory power.  Red dotted line is factory torque.  The green solid line is rail chip power, the green dotted line is rail chip torque.  Blue solid line is ECU tuned power, the blue dotted line is ECU tuned torque.

As you can see from the graph power and torque from an ECU tune gives maximum power and torque between 1700 and 2500rpm which is where most driving occurs, and all over the rev range, we have gained power and torque over standard.


Feedback from customers has been better fuel economy, no hesitation when overtaking, no need to change down gears when driving a steep incline, safe power increase no lurching power makes it easy for anyone to safely drive.

What power figure will a Power Curve Performance Diesel ECU Tune give me?

The standard result advertised for Australian Common Rail Diesels is 30% Power and torque and 5-25% fuel economy.

Through out our time ECU tuning, we know that each and every vehicle is different.  At Power Curve Performance each ECU Tune is fit for purpose.  Tunes are designed for the engine and customers driving needs.  We will sacrifice top dyno figures for better down low driving power.  An ECU Tune is not a high power option there is no 500hp gain.  We are looking a drivability and engine reliability results.

Each make and model will be different so is each individual vehicle.  A Toyota will start at a 30% gain and climb from here.

We do not give a fuel economy figure based on the individuality of the engine and drive style.  If you own a highly loaded big tyre 4×4 and lug it around you will not improve your economy.



What else can I do to improve my performance with my ECU Tune booking at Power Curve Performance?
