Looking for more punch from the turbo in your 2011+ 135i? This is the perfect upgrade for someone who wants a dramatic but safe boost in power - especially in the low to mid-range. Our software opens up the N55 engine's potential, delivering big gains in torque from idle all the way past 6500 RPM! The torque is especially improved after 2500 RPM, eliminating a pesky dead spot in the factory programming. This is a HUGE torque that is a NIGHT AND DAY difference!

Our software is not just an increase in boost; we're not fooling the computer into making boost. This is a total re-write of the stock software, making power by adjusting the ignition and fuel mapping and boost. We have tuned for part throttle response as well as full-throttle with special attention given to ensure the correct, and safe, air-fuel ratio. Please keep in mind that with a "turbo car" it is "easy" to make horsepower by increasing boost BUT keeping your BMW reliable is the most important thing to Turner Motorsport.

This software is a reflash of your computer. The computer will need to be sent to Turner Motorsport for the installation. Click here for specific instructions on shipping the computer.
