well i decided time to fit this and see what difference if any it makes.
fitting went well and took about 30mins to do.
started the car and, oh no it was going on 3 cylinders and sounded rough.
also managment light was on.
switched off right away and off to my work for the laptop to see what faults codes had come on.
got back with the laptop plugged it into the diag socket and started the car to see how it was. it was running fine, firing on all 4 and light off.
read the codes anyway and it was misfire on cyl 3 and 2.
erased the codes and off for a test drive.
WOW what a difference. the turbo kicks in as usual around 2500rpm but once the revs get over 4k it pulls like mad. feels like the turbo kicking in again.
so for £20 to get a cam it was well worth it
