The ultimate chip upgrade for the S4 4.2 engine is available from APR. After months of long nights and many hours of dyno work we are pleased to offer you chip tuning that is second to none. APR has worked hand in hand with many customers to deliver a chip that works. Expect increases in throttle response and a smoother, more powerful top end. APR chips are available in an octane specific version for the octane of gasoline that you typically run in your car. The power that the chip makes also depends on which ECU is in your vehicle. The S4 4.2 ECU can be upgraded with either the use of a soldered in EMCS module, or DirectPort Programming. For more information on DirectPort Programming, please see the DirectPort page.
