VAST is pleased to present a huge step up in HP(25hp) and TQ(30ft/lbs) for the 4.2L N/A engine in the B8 RS5. We are confident to say that our tune is one of the strongest RS5 tunes in the country, and fully tailored to the environment we are flashing it in. We do not cookie cutter tunes as we try to optimize every tune we create for the hardware, gasoline, and climate the vehicle is operating in.
We are able to port flash these files through the OBD port in the RS5 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 B8 RS5 must be performed at VAST Performance.
