Hello chaps, I need some help please. Where is the tuning box located I bought the car about a year ago and it just doesn't feel as quick anymore. I just thought a visual inspection may show something like a loose wire, thanks in advance for any help

It is under the cabin air filter - top right of the engine compartment as you look at it when standing at the front.

It is easy to get used to the torque....
