DINAN + PERFORMANCE ENGINE SOFTWARE - BMW S63 (TU4) ENGINE

Some of the world's most potent sedans and SUVs to begin with, the F90 M5 and F95 X5M now have the ability to go beyond formidable and to levels of outright domination in their respective classes. With max gains on pump gas nearing +115 WHP and +160 lb-ft of torque courtesy of Dinan + software the battle for runner-up in each respective class is the only question.

Those are garish gains on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive feat. 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.
