• Dinan releases Stage 2 BMW N55 turbo six cylinder performance software - $1999 and 355 horsepower

      Dinan has released their Stage 2 Performance Software for BMW's equipped with the N55 direct injected turbo six cylinder. It is currently available for 2011-2012 BMW 335's (including X-drive), E82 135i, and the E70/E71 X5 and X6 35i. Applications for the F10 535i and F25 X3 xDrive35i are coming soon. $1999 is a bit on the high side but one can be very confident in choosing Dinan and the Dinan supplied warranty in lieu of the BMW factory warranty is always an attractive option for owners concerned about any potential issues. No dyno graph provided as usual and we wish Dinan would get out of this habit.

      After hundreds of hours of hard work by the Dinan engineering team the N55 Performance Software is now available for immediate download via OBDII at all Dinan Dealers around the world. Dinan, the most trusted name in the BMW aftermarket is now offering the most anticipated Performance Software in years and as always is covered by the most comprehensive and longest warranty, a BMW new car factory matching warranty coverage up to 4 years / 50,000 miles.

      It is well known that the N55 engine software has been a tough nut to crack. Our 4 full time software engineers were able to make a blistering fast software tune 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 (X5 & X6 top speed, 155 mph), enabling the BMW to achieve its full potential.
