A8 4.2 TDI - Are they normally this slow?

[sutherland]

I eventually got my throttle body replaced and a DPF regen, which improved performance and stopped a wailing noise caused by back pressure. However, I still think the performance is not what it should be--at least it's a long way from published figures. I get the following best figures:

0-60: 6.7s
1/4mL 16.1s 99mph

Does anyone else out there have an Torque Scan running on their Android phone? If so, and you've got a 4.2 TDI, I'd be interested to know what figures you get for your car using the realtime information. Perhaps the claimed figures of 5.7 secs are actually miles away from the real world.
