E34 525i 91-95 Turner Conforti Performance Chip

Need to breath more life into your engine? Add a Turner Performance Chip! These chips were tuned by Jim Conforti on the dyno to maximize the engine's efficiency when using 91 octane gasoline. The result is more horsepower and better torque - especially in the mid-range of the RPM band. Just because your car is a heavy 5-series doesn't mean you can't make the car faster, more responsive, andsmoother-running. The car really feels more alive! There are several different chip options, please let us know if your car has any modifications.

Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall drivability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour. Click here for installation instructions.
