Default My McLeod twin 1200 HP rated clutch is slipping

So I have exceeded it's rated power capabilities. I will call them Monday but anyone have any great ideas? I am hoping I don't have to buy all new everything. The clutch is broke in only, 500-600 ish miles. We were dynoing the car again tweaking the tune and had made 945 to the tires before and we have duplicated that but as soon as we added 2 lbs of boost (knowing it will break the 1000 rwhp mark) it lit the clutch up. I have the correct gap between throwout and clutch. This is the "borg/beck" style clutch. I throw this out there because someone here always has been there done that so to speak.

Pretty weird. At what RPM are you shifting it?

Is this the "Original street twin" clutch? Or the RST or RXT?

Its the borg and beck style. It has 3 fingers not the diaphragm type in the pressure plate. Its twin 10.5 inch frictions that are solid linings not "pucks." I am just out powering it. I am hoping they can add spring pressure to the plate or reline with different materials. Or both. This would be way cheaper than a whole new clutch assembly.
The thing slips on the dyno and on the street if I swat it in 4th under 80. The dyno is load bearing so its like the street.

Taner, are the Miba discs puck type or solid?

I had Miba discs built for mine locally, but they were puck style.

Just curious what to expect with 600ish rwhp.

taner was correct. I got the clutch assembly sent off today. They are going to reline with Miba lining and look into adding spring pressure.
