Tarmac Engineering has spent countless hours to deliver the most diverse tuning package on the market. We looked at what the current market was offering and noticed missing elements that customers required so we developed something we believe you will be truly happy with.

Feel comfortable knowing that the tuning experience we offer hasn't just popped up overnight on the internet. It's been in the industry for over 20 years. We aren't talking about one particular brand of car either, we're talking about almost every car manufacturer on the market. From rough and tough 4WD's like the Nissan Patrol to the elegant powerhouses like the Lamborghini Gallardo. Literally thousands of road and race cars have been tuned by us all over the world.

All our tuning development is done on real cars in the real world. We have a fully approved environmental Dyno cell housed in an acoustic chamber. This facility allows us to tune all types of vehicles to perfection without disturbing our neighbours. We carefully tune each vehicle keeping a close eye on the vital components of the vehicle, from the air fuel ratio and timing to the fuel delivery and of course keeping in mind engine longevity. We do extensive road testing and road logs and then take cars to the track to test extreme conditions. We leave nothing to guess work, everything is safely calculated to provide the best result.

The year is 2016. Annoying multi button or switch button controllers are a thing of the past. With our colour LCD touch screen with large app style buttons we have made it extremely easy for you to use. Anyone can use the SpecTune controller.

Factory Tune

This option is very popular for people that often leave there car with a 3rd party, whether it's a hotel or car cleaner. This limits the power and the vehicle cannot be taken past half of its total rpm range. Excellent safety feature.

Linear Tune

This tune is design to be super smooth. Bringing on the power smoothly is perfect for the person that is happy with the factory tune but wants a linear increase in power across the entire rpm range whilst still providing the maximum achievable power suited to your modifications.

Aggressive Tune

This is our most popular tune. This tune brings on the power as quickly as possible. Feel the rush as your turbo brings on the torque and plants you firmly into the seat. Engineered for maximum performance in the low, medium and high rpm range this tune will certainly excite you all the way to the redline.

Motorsport Tune

This tune is for motorsport use only. Please contact us for this option.
