Cadillac CTS-V - new ls7 clutch slipping!! need help

Have ls7 kit slave flywheel everything and have 980mi on it and finally got on it and it's slipping when I shift hard and in 4thu while im making a pull??? Idk what to do or check im pissed never had this issue w a clutch and I go own and have problems

are you sure it's slipping?

It's hard to make your TC go off in 4th but they kinda have the same syptoms

Its not traction its reving up

was the clutch kit brand new when you bought it?

I havent really gotten on mine yet, but with ur mods, you shouldnt be slipping

Did you give it enough time to break in?

Brand new and yes babied the hell out of it for 980 miles. And it only slipped hard in the middle of 4thit hooked in the other gears

I had mine on the dyno after 500-600 miles and it held several pulls of 450 rwhp in 4th with no problem. How much power do you have?

351.75 to the wheels
