from what i gather the psd 65mm toothie kit is approx 65mm.. maybe ever so slightly  bigger.

Many vee belt pulleys are  often actually slightly smaller when you measure them

Also the in and out play can mean a worn bearing or shaft or oil slinger ring on your charger

are you sure the boost gauge is reading right, no air leaks in the line to it?

yeh i did have a problem with my bottom boost pipe it kept popping off were i dident fit it properly but after that i sorted that problem. otherwise i cant think of messing around with any other boost system. oh well i guess it is on a tiny bit less not major and as pete said the seal can be worn with that play i have. so i think i should get a rebuild it hasent been done for 2 years.

thanks for your replys guyz you 2 always come to my aid  ;D
