Your Top Speed on 550 TT with Tune
Just wondering if you ever gone over the 160mph with the tune.
Mine got to 160 in no time and stayed at that mark "Alpha tune", wondering if i'm limited to 160

Wish I could say I knew. If you're in the New England area and happen to own a private road I'd be happy to attempt a top speed run at some point When my ECU removed the OE tune the limiter was supposedly removed, but I haven't had a chance to verify.

Sounds like the factory limiter (which is 159?) is still in place.

Is Alpha Tune a well established one?
I am used to BMW tuning and was able to trust Dinan. I am not sure if there is similar tuner with similar reputation and reliability for MB. Perhaps Renntech?

The speedometer does not show speeds beyond its analog scale. So for example: My scale ends at 260km/h, therefore the speedometer (also the digital speedometer) showes 260km/h even if I am going 320km/h.

I think that exactly what it was, it got to 160 that is 260 km/h and just stopped there , i will use gps based speed detector if i ever go that fast.
