Instruction Booklet For The Air Walker Audi A4 Turbo 0-60 Really Slow?!?

Audi A4 Turbo 0-60 really slow?!? - instruction booklet for the air walker

Hello,

I have a 2005 Audi A4 Turbo with B7-wheel drive, and is an automatic.

The manual says it does 0-60 in 7.7 seconds for the automatic version, but when I try using a stopwatch or a camera and put the vid in slow motion is more like 9.5 seconds ...

I tried the car in all types of automated modes (auto,) sports cars, moving paddle, and they are all very similar ...

Someone knows what can be? the turbo maybe? Transmission? Air filter or injectors, or what?

Please give me an idea of what could happen?

Thanks
