Focus ST Boost Solenoid Valve

Focus ST Boost Solenoid Valve
Evening each !
So driving the focus yesterday - gave it some beans in 4th gear , seemed to make a lot of noise with not a lot of go.... [no clutch slip, just felt boostless] , put it down to me imagining it ...,
Drove the car to work this morning , came onto stretch of dual carrigeway , planted it in 3rd , seemed to shit itself a bit "surging" with the boost gauge needle doing a nice dance ! ,
seemed ok coming home boosting into the red as per normal [DSCi map] , dropped the lad off I work with , and pulling away 1st and 2nd jus seems a little bit "lazy" coming on boost to what it did , and I could sware under light throttle in 6th gear whilst crusing it was whistling a little bit more than usual ...,
Intermittent at present so not **too** worried , but im led to belive the boost pressure solenoid valve [on side of turbo i think ???] is common as muck on them ,
which leads me to the question[s] - which is the best uprated one , and has anyone done one , what they like to change ??
Many thanks !

Elevate, IPD and Pumaspeed do uprated versions mate. Ring pumaspeed and ask them as there was a group buy for one of theirs for £77.99 posted. Otherwise ring JW-Racing and ask for an Elevate one and see what price they can do but more expensive.

Mite be worth just having a quick look around for boost leaks aswell, the metal boost hose that runs underneath between the sump and gearbox can sometimes crack.
