Dinan® Performance Engine Software for BMW X1 X5 X6 xDrive35i N55 Engine Stage 2

The Dinan® Team made a blistering fast software upgrade, using our 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.

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 stock top speed governor is retained for xDrive vehicles.
