Clutch help

running a brand new centerforce dual friction, and in second gear as soon as the car sees boost at about 3700rpm it instantly spins the clutch to 6000+. its a 3300 pound car that makes about 600hp and 650 ft lbs, i checked the clutch for oil and its ok.Who makes a good clutch that can handle the power? ive had a dfx centerforce before but didnt like how little pedal feel it had, anyone have any experience with fidanza 4.3 etc? i want to stay away from twin disc set ups. the odd thing is on the dyno it didnt slip at all.
