clutch problems i think

well ive broken in my dcr ps2 clutch for 700 miles and its holding the boost good but im having a problem when i press down on the clutch there is a loud screeching noise when i go to shift to the next gear and the noise only happens when im high in the rpm's. i have only done third gear pulls like he says after you have broken it in and i havent shifted it hard, ive followed all the steps. and no its not an install error because the man who did it for me is a transmission specialist and has been building and working on race and regular trannies for over 20 years. a couple people have said it sounds like a TOB(throwout bearing) but it shouldnt be because they come with a new one or unless i got a wrong one because dcr was having a problem with sending out the wrong TOB's at one time. but i dont have no way to tell if its wrong because the box is thrown away. and be4 all you dcr people come in here and say wont you call him or send him a pm i have done both no phone call return or pm back. im not trying to bash him i just would like to know whats wrong if someone has had them happen to them.
