Clutch Slipping Bad Mounts

[talon2gb]

Hey guys, about 2 months ago I replaced my clutch with and oem one (I know it was a mistake), when I first changed it I beat on it without breaking it in, and therefore it slipped a little. The slipping went away for awhile, but now it has returned. It won't slip in 1st or 2nd, only in the 3rd, 4th, and 5th when I hit full boost which is 8psi. I did some research and found out that the slipping in high gears could be caused by bad mounts. Here's the link 5th and 6th gear slip when boost hits - Rennlist Discussion Forums

What do you guys think it could be?

i think slipping in high gears means that the clutch is slipping because its shot. higher load on the clutch in the higher gears.
