Pain in what way mate?

what else will i need to make the most of it?

my spec so far is....

Bailey evo dump valve.
Samco boost hoses, in red.
-31 actuator.
Magnex full exhaust, with 4" rolled tailpipe.
Boost gauge.
Drilled airbox, with K&N filter element.
Uprated clutch.
Uprated fuel pump.

Looking to get a nice FMIC & a chip soon too.

Just realised aswell, it comes with some pipework for the IC, but dont know if its for std or uprated
