Japanese-engineered Afterfire & ECU Tuning
This 2022 GR Supra throws sustained flames on overrun – the hardest afterfire of any car we have ever tuned. The catch: its factory-locked ECU. Full story of the bench unlock and the custom pops and bangs calibration behind the dragon afterfire.
If you own a 2022-or-newer A90 Supra, you already know the problem: the ECU is locked. Standard flashing tools can’t read it, can’t unlock it, can’t touch it. Most shops will simply turn you away. We didn’t. This is Japan’s first pops and bangs build on a bench-locked late-model GR Supra — and here’s how […]

Godzilla, tuned where it was born. This R35 GT-R belongs to a repeat client of ours — a collector who has already trusted us with his Maserati and his Ferrari. This time, he handed us the keys to Japan’s most famous weapon. What we built: How Much Power Does an R35 Make? (Real-World Reference) Numbers […]
