Audi B7 RS4 4.2 FSI Tuning

VAST is pleased to present a huge step up of 25hp and 30ft/lbs of torque for the 4.2L Normally Aspirated engine in the B7 RS4 We are confident to say that our tune is one of the strongest RS4 tunes in the country, and 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 flash or port flash these files through the OBD port in the RS4 without the need to remove the ECU. We can also create backup images(extra charge) of both engine computers 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, raise the rev limit and deliver smoother than factory timing and fuel maps.

- At this time, all tuning on the B7 RS4 must be performed at VAST Performance or you may ship your engine computers in for bench flashing and we can ship them back to you.
