This good old Mitsubishi Evo was in for a Dyno Re-tune. As any car advances in its age, its unavoidable that some of the key engine sensors start to slow down, their values change, and components wear. In order to combat this at Tunehouse, we conduct a health check and re tune the ECU to ensure everything continues operating perfectly.
Results?📈
Power went up from 235 to 249KW.
Torque increased from 380 to 401Nm.

Another Kia Stinger GT custom calibration complete!
With Jim behind the laptop, we achieved excellent gains of +50Kw & 56Nm of torque when comparing peak numbers, all on 98ron fuel.📈
Most notably however, is the significant increase we obtained in the midrange delivering a much more enhanced and engaging driver experience.
In simple terms, not only does it put you in your seat now, but it keeps you there as well!

One of our clients recently came through our shop with his beautiful Audi RS4 for a THR stage 2 package.🛠️
This Package included the fitment of high flow catted downpipes and off course, our custom calibration which was conducted in our state of the art dyno facility.💻
Results? Apart from now being able to hear its 2.9L V6 sing its lungs out, we obtained a peak of roughly 347Kw & 744Nm of torque to all four wheels!📈

This isn't your ordinary Holden.. This VL commodore, last of the Peter Brock Specials, was just in for some tuning love from the master himself, Jim Ghelis.
Integrating old school with new tech, Jim dialed in the fueling by adjusting the jets, set the timing, and configured map switching for different fuels. This coupled with some other touches and this naturally aspirated V8 is now pushing upwards of 380Kw at the wheels!

This Ford Ranger Raptor was in for a THR Custom tune after our team installed a Process west intercooler piping kit.
With Jim behind the laptop, we saw some strong numbers out of this raptor however it was evident that the factory intercooler was starting to reach its limits. We typically see excellent gains with the platform, those being power figures exceeding 300kW to the wheels on 98 with both our Stage 1 & 2 packages.
If you're looking to get some work done to your Ranger Raptor, be sure to flick us a dm!

This immaculate Audi RS5 was in for a THR custom tune as the owner was after a bit more power than what the car had in its factory configuration. After running the car on the dyno and adjusting the factory calibration, Jim was able to extract an additional 55kW, bumping up the power to 290kW at the wheels!📈
Its fair to say that this car not only looks the part, but it drives the part as well now.
