hi,got a clio 1.8 16v with piper cams and adjustable pulleys,so its currently running rich,if i put i power boost valve on aswell would this make any difference? would it need tunning? thankyou

You'll be running lean not rich (needing more fuel)

Tat

Get it properly mapped

get a new NKG lamba sensor. Worked a treat when mine was rich. Actually a slightly faster car afterwards!
Power boost valves are slated by most people on this forum, I've got no experience of them but im told they will run the car richer

wouldnt it of got mapped when the previous owner had the cams fitted?
