TUNING THE SUBARU EJ20 (WRX)
This Impreza came in running a big eBay turbo which, unsurprisingly, wasn’t doing it any favours. Response was pretty lazy out of the box, but after a series of careful reflashes and optimisation runs, we dragged every bit of usable performance out of the setup.
Even with the limitations of the hardware, the car left significantly quicker than it arrived. The final tune transformed the way it pulled through the revs and delivered a night-and-day improvement in overall driveability and performance.
