Audi S4 -  ECU and hardware upgradesken.s4.shopped.01.jpg

 The ultimate chip upgrade for the S4 2.7T engine is available from 2B APR.  We are pleased to offer you chip tuning that is second to none. We have worked hand in hand with many customers to deliver a chip that works. Expect huge increases in low-end torque, improved throttle response and a smoother, more powerful top end.

 The chip is designed to operate within the turbochargers' efficiency range. Some 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. Please see the chart below for more information.

 All APR chip upgrades use encryption, which serve several purposes. First, it keeps prying eyes out of our software and prevents lesser companies from copying the chip and degrading the product. Secondly, the encryption prevents the dealer from flash programming the ECU. Also, all APR software is undetectable to a dealers VAG diagnostic tool.

 All APR chip software comes with lifetime free upgrades-you only pay for the labor time. There is also a lifetime warranty against defects in the software or soldering. All chip upgrades have a 30-day Money Back Guarantee.

New B5 S4 Stage III Software Released
APR has retuned our software for the B5 S4. Utilizing new tools and techniques, the B5 S4 Stage III now outputs 447hp and 467lb-ft on 93 octane pump gas, and 485hp and 498lb-ft on 104 octane gas. Even more power with 2Bennett custom additional components.
