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.

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!πŸ“ˆ
Its fair to say that this car not only looks the part, but it drives the part as well now.

1:41.94!🏁 Last night was a long-awaited track night for our team over at Sydney Motorsport Park. It was a perfect night with great conditions and our GR86 project car was ready to go after we made some minor tweaks and bumped up the power!πŸ“ˆ
With Boz from behind the wheel again, a PB was bound to happen and happen it did with him setting a time of 1.41.94 ⏱️. For perspective, our previous PB was a 1:43.02 and in stock form our 86 managed a 1:51.68.
Stay tuned for a video coming soon which will cover what's been done to achieve those times and what the data shows!
Big thanks again to John Boston from track school for bringing the vibes and most importantly, giving us valuable driver feedback so we know exactly where to go from here with project THR GR86πŸš€.

Got to love those soft limiters🫀 This beautiful Porsche Cayman GT4 came in for a quick exhaust upgrade, replacing the factory rear muffler for a premium Akrapovic unit.
Although we don't get to enjoy the full spectrum of sound across the rev range, you guys will have to use your imagination for the full 9k RPM this flat 6 can spin to!

8Y Audi RS3 Stage 2 complete! That beautiful 5 cylinder can finally be heard thanks to the Veltiston downpipes we installed.
Aside from the massive audible improvements, after tuning the car this RS3 obtained an additional 55Kw that it never had, taking it to 290Kw at the front wheelsπŸ“ˆ.

This GR Corolla was initially in for a basic service and a general check over, however somehow it accidentally ended up on our dyno!😜
It will now be driving out of our shop with an extra 25Kw peak along with heaps more midrange grunt and torque. Not bad for just a serviceπŸ“ˆπŸ˜‰.

Another Suzuki Jimny in for a custom Tune! This one's equipped with a manual transmission and has finished up with some impressive gains over stock, that being +11Kw at the wheels! Yes.. it may not seem like a substantial gain however for a car that only started with 45Kw, +11Kw is a 24.4% gain!
After Jim finished tuning the Jimny, we test drove it to make sure those numbers were reflected on the street and were further impressed with the difference those +11Kw and corresponding gains in torque made on the overall feel and drivability of the car.
We are excited for the future with Jim and the Jimny's, who knows how much power we can get out of a supercharged one.. πŸ‘€
