Special Product Notes
The legendary 5 Series has been reincarnated with the F10 chassis and the N63 4.4L V8 turbo motor. The beauty of the turbo motor is its ability to be tuned to make impressive gains just by upgrading the engine software and the N63 motor is no different.
The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related re-calibration producing a maximum output of 495 horsepower at 5000 rpm and 573 lb-ft torque at 3500 rpm.
The Dinan Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. In fact, over 2000 lines of code have been addressed, producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product.
With Dinan’s software, your 550i will be capable of achieving its natural top speed as the governor has been removed. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.
