DYNO DEVELOPED POWER GAINS WITH NO DOWNSIDE!
Max HP gain = 60 hp
Max Trq gain = 70 ft-lbs
Rev Limit = 6900 RPM

Dyno developed performance software for the X6 35iX (twin-turbo N54 engine) - and it makes AMAZING POWER! +60hp and +70lb/ft of torque over stock! There are no down sides of this modification, other than needing 91 or higher octane gas. We modify fuel and spark mapping, adjust the valvaetronic (throttle), and most importantly INCREASE THE BOOST to a safe, reliable amount.

This is the perfect upgrade for someone who wants a dramatic but safe boost in power -- especially in the low to mid-range. Your car will have MUCH more torque at ALL RPM, including down low (where you want it) for remarkably better torque. This is 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.
