What should I do?

[S2tuner]

A car on a dyno would never show any speed, because it's standing still, even though the wheels are spinning at whatever equivalent of road speed. I'd definitely have a word with the people involved.

well i guess if it was my car that i would not be posting on here at the moment as i would be spending another night in the local lock up. They or somebody has taken the piss out of you and there is no way i would let them get away with it.

Im well and truly peed off and its not even my car!

Grant why are you even asking the question on here? Go back to the tuner (and name and shame on here) and tell them of your findings.
