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 able to port flash these files through the OBD port in the RS5 without the need to remove the ECU.
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.
