Dinan?Stage 2 Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling. Dinan?s software also removes the top speed governor so the BMW will be capable of achieving its natural top speed. Producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. In an effort to more effectively control oil and water temperatures, the Dinan software actually increases water pump speeds as boost pressure increases. 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.
Increased boost pressure exceeds the turbochargers? design limitations at higher rpm, potentially shortening their lifespan. Dinan?addresses this issue by tapering the boost gradually at higher engine speeds. This approach also addresses the fact that with increased boost at higher rpm the turbocharger temperatures would exceed the intercooler?s ability to cool the intake charge, resulting in a loss of power and compromising the long-term durability of the engine. The tapered boost along with the required oil cooler keeps temperatures within the design limitations so as to optimize output and ensure engine reliability with the added boost pressure.
When BMW creates a software update so do we. Dinan?will make software available at no charge to keep your car running as well as it possibly can.
The results of Dinan?s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 378 horsepower at 5700 rpm and 415 lb-ft torque at 4300 rpm when the software is combined with the Dinan?exhaust, intake, and oil cooler.
