After many hours of further research, tuning and testing Dinan have improved on their hugely popular Stage 1 Performance Software. Their team was able to make Stage 2 much faster by improving turbo response across the power-band. This tuning is especially noticeable in the first two gears, now catapulting the car off the line. Tuned for a smooth power-band to put down predictable and even power in all gears and throttle positions. This smoothness improves the quality of the shifting and the overall drivability.
With Dinan’s software, your 650i 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.
