AMG Perforamce pack E63

[P30egy]

Hi just got a E63 2010 plate which as the performance pack apparently. I used one of the Russian websites to get my spec sheet.
Anyway after trying the top speed put it seems the limiter kicks in at 155.
Do I need be in manual or is the website incorrect. Thanks

Does it say P30 in the datacard. In this case the top speed should be limited to 174mph.
