CRTD4 – No Safer Way To Tune Your Vehicle.


With the Infiniti brand always pushing the boundaries of automotive engineering, their vehicles and our tuning solutions work perfectly together. As with all manufacturers, Infiniti produce many models using the same engine tuned to different levels allowing us to untap this performance with our tuning boxes.

Our CRTD4 reads and adapts the live data from the engines sensors to increase the performance. We use the fuel rail sensor data to alter the air to fuel ratios within the combustion to create a better, stronger burn producing more BHP while also increasing fuel efficiency. Our Twin Channel Tuning Box also connects to the boost sensor to get the turbo to spool quicker reducing turbo lag. All of these changes are made instantly to provide a better, smoother drive while staying within the safety limits of the ECU.
