Cheers for the help was just after info thats all if it can't be adjusted then surley he would need a new actuator he might not have one in stock etc, was just after some more info on the difference between -31's and standard and trying to work out the one i have, the only way i can see this one adjusting to 15psi would be by cutting the shaft but then surley this would mean your pushing it to do what its not mean't for, either its faulty and should give higher psi at given adjustment or its not a -31, i've been told before a -31 should give a minimum of 10psi, the rod had about 8 turns left when it was at 10psi i turned it about 7 times to get it to 12psi, and now i can't adjust it any more, i would rather do it myself all ready for a drive to the tuners than stand around down there or wait for him to get the parts in etc,

So just after some info thats all thanks for the help so far
