Why is my car faster than stock?

I don't know if there is or not, was just a suggestion somebody said. But again I don't really know how likely that is. Will get an engine bay pic in a mo.

Take it to a garage and have it smoke tested for leaks. Cheap diagnosis.

Well here she is... to be honest I am not expecting some magical answer from anyone, it's just bugging the hell out of us. Plugged in diagnostic equipment too and no error codes apart from this secondary air flow code thing which seems meaningless. wipe the code and it comes back every few hundred miles.

Standard AUQ apart from the forge valve from the pic.

Easiest way to tell would be to run logs on VCDS and log requested vs actual boost. That way you could check if it's mapped, and if it has a boost leak at the same time.... No real way to tell apart from that. Although i don't think you would have a nice smooth torque curve like that if you did have a boost leak.
