D900-31TC Stage 3 Performance Engine Software N55

Product Description

Get 373 horsepower and 408 lb-ft of torque out of your turbocharged BMW engine while keeping everything you love about your BMW, including the warranty coverage. The Dinan Engineering Team made a blistering fast software upgrade that will push your guts into your spine, smoke the tires and put a big smile on your face. Using years of experience tuning BMWs for the street as well as winning back-to-back Grand-AM DP Championships and the 2011 24 Hours of Daytona the Dinan team is the best in the business.

Dinan Performance Software is so much more than just tuning up the turbo boost. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. Protecting your BMW while giving the most performance is the definition of “Performance Without Sacrifice”. Drivetrain and engine components are analyzed for strength then the program is tested on the dyno and in the real world for durability and drivability. Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. The top speed governor is removed, enabling the BMW to achieve its full potential.
