Just wrapped up a tune on this 2008 EvoX GSR . This car still had the OEM fuel pump relay and with 80k miles, the relay was beyond dead. 15.5 AFR at full boost. We were lucky enough to catch it but we’re not sure how long the car has been running this way. Either way we made 340hp 335TQ at 25psi. We also pointed out and fixed other small issues and she runs smooth as butter.
Please make sure you have the updated relays. It will save your motor.
