really really easy...
BUT you will need, absolutely must have, a boost guage for this.. if not you run the risk of overboosting, and popping your head off, at very worst you will get silly heatsoak, i got mine as a little kit from Rspec, off of ebay, guage is spot on accurate (tested it at a mates work, he works for bosch diagnostics and chucked it on his hideously expensive calibration machine for things like this)
go to halfrauds and get some 5mm id silicon boost hose (its £10 for 2 meters, or get it from somewhere like roose motorsport or ebay - it must be rated as boost hose).
get some GOOD quality appropriately sized hose clamps for this job.
1. remove the small rubber hose that connects the turbo housing (cold side) to the actuator completely..
2. run a line from the turbo housing, to a T peice, then to the "in" side of the boost controller.
(2a. from the T peice run the contained line to the boost guage (this should be BEFORE the boost controller))
3. from the "out" side on the boost controller, run to the actuator diaphram on the turbo..
So..
Turbo manifold --> T peice (to boost guage) --> boost controller --> wastegate actuator.
wind the boost controller completely off, it will crack open early, and the turbo will behave as it was before, make sure the boost guage is working appropriately (it should be showing around 12psi), Then wind the boost controller in i would say in 1 turn incriments max, until you reach about 16psi for now.
anything over 18 or so without decent intercooling will suffer from heatsoak, and you will lose power
the boost controller serves 2 purposes, it regulates the pressure to the actuator, so you dont get wastegate creep (it starts to open before the required pressure due to the increase in pressure in the turbo itself) which means your boost build will be better, and it allows you to keep the wastegate closed until higher pressures by only allowing the pressure through at the pre-determined point, regardless of what the actuator is set at.

Given the choice between Niall and the sheep. I would choose the sheep!
