DINAN + PERFORMANCE ENGINE SOFTWARE - BMW N63 (TU3) ENGINE

Even though a step below the S63TU4 and the immense power that that M engine wields, the N63TU3 still shares much of the same V8 architecture and is plenty capable of feats most powerplants can only imagine. Paired with a Dinan + engine calibration yielding max gains on pump gas of +81 WHP and +123 lb-ft of torque, the N63TU3 and the M550i/M850i it powers, instantly evens the playing field and puts the platforms on level footing with the alphas of the brand. The imposing gains are eye-opening on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive achievement. Going one step beyond simply power and including a factory matching new car 4yr/50k warranty you get a performance value proposition that is hard to fathom.

While increases in power at this scale typically come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan's calibrations are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labelled as being the smoothest, factory-like solution in the marketplace.
