There are no real world experiences to share??

Btw, I was just looking at the Dinan website and noticed they already offer a stage 2 of their software for the F10 550 (

Although the gain is minimal (+6hp and +7lb-ft) over stage 1, it appears they changed how the power is delivered to be stronger down low especially in the the first few gears. From the website,

"Our 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."

Hopefully they continue pushing development on the N63 engine and something like this will be available for the X5/6 50i soon...
