Yes that includes delivery.
But it is better to have them fitted and a remap , I will post a dyno plot up later what happens when you fit Berks on a tuned car without a remap , your cars need a remap if you fit these in my opinon.
The 313bhp like a remap without anything else as they are super rich from the factory, but fitting the berks I would say they will definitely give a bigger punch in the midrange and a few more BHP at the top end.
But have the job done in one go it saves you a few quid in the long run , but dont worry about fitting Pop chargers these get terrible heat soak while sat in traffic just stick a pair of HKS filters in your stock airboxes.
