VAST is pleased to present a step up of 15-20hp and 25-30ft/lbs of torque for the 4.2L Normally Aspirated FSI engine in the Audi Q7 and A8 platforms. We are confident to say that our tune is one of the strongest 4.2 FSI variants in the country. It is fully tailored to the environment we are flashing it in. We optimize every tune we create for the hardware, gasoline, and climate the vehicle is operating in.
Our aggressive optimization of a more controlled and targeted fuel curve for power and safety, demanded load control and ignition timing brings up airflow gains unrealized in factory form in order to take full advantage of a normally aspirated motor.
We are able to bench or port flash these files through the OBD port in without the need to remove the ECU. We can also create a backup image(extra charge) of the engine computer to keep on hand for you in case you ever have hardware issues down the road.
Take advantage of the power gains while retaining the factory knock protections.
We are able to deliver substantial power gains with smoother than factory timing and fuel maps.
- At this time, all tuning must be performed at VAST Performance or you may ship your engine computer in for bench flashing and we can ship it back to you.
