The ultimate K04-015 turbo setup.
Almost everything you need to run E85 on a BorgWarner K04-015 setup! Our meticulously engineered K04-015 tune is one of the most effective upgrades available.
This tune is specifically designed to get the most out of a K04-015 on a stock block and fuel pump. Our E85 tuning kit has everything you need to be race-ready for less than buying each item individually.
Multi-Tune is automatically included in this package. User Adjustable Launch Control can be included for dedicated track vehicles with a manual transmission vehicles and straight pipe. Rolling Anti-Lag is only available for MY2001 competition vehicles and also requires a manual transmission and straight pipe. No Lift Shift can be included on request if User Adjustable Launch Control or Rolling Anti-Lag is selected. Pedal overlap is available on request at no additional charge and is compatible with all transmission types and exhausts with the purchase of this kit.
This tune can be set up for any four fuel types on wideband ECUs and two on narrowband. If E85 is not available near you, feel free to take advantage of the savings this kit offers and select “custom” for your MTC option. Multi-Tune can be set up for any octane or RON rating*, E85 or lower percentage blends of ethanol, water methanol, econ (stock boost/timing levels), a “dead map,” or varying boost levels.
*While we don’t suggest running anything lower than 91 Octane/95 RON for best performance as suggested by Audi, we can accommodate customers in countries without access to 91.
This tune package can accommodate upgraded rods and can be used with the stock MAF, stock MAF sensor with TT225/VR6 housing or a complete TT225 or VR6 MAF. This tune is not intended for Hybrid K04 builds, heavily modified blocks, cams, blow through MAFs, custom MAF housings or housings other than TT225/VR6, or 3 bar MAP sensors.

Most MY2000 B5 A4’s in North America have a narrowband ECU and O2 sensor. For narrowband vehicles, MTC can accommodate two maps rather than four due to the size of the ECU. Please contact us with your ECU part number if you need confirmation on your ECU type. For B5 A4 owners outside the US, we suggest emailing us with your engine code and ECU part number before ordering and confirming that your vehicle is using a port flashable ME7 ECU and electronic throttle.
