First off bluefin and de-cat together.. A lot of people rate the dreamscience as a form of re-map too.. Then see how you get on, you may decide to go for a manifold after that ... or maybe an uprated Forge actuator ... or maybe an uprated chargecooler rad ... or if you`re into driving hard all day on track a front mounted intercooler

And so it goes on
All starts to become personal preference and what you want exactly from the car.
But the above mods should see your 280bhp target
Also would recommend that you make sure that you have the `AE` map on your car ( from Ford ) as it is more preferable in most people`s opinion ( including mine

)
Hope this helps and doesn`t confuse!!
