2006 clutch/flywheel question

[2006subaru]

hey

so i have a 2006 stage 2 wrx and installed a exedy stage 1 organic clutch and exedy lighten flywheel

broken in properly and all that

after the break in i decided to punch it.

i would do a roll in first to say about 2500 rpm and punch it to about 5500 rpm.

when i depress the cluth i hear a almost knocking sound coming right from the shifter.

this only happen when i am rolling in first and then punch it.
and only happens when i depress the clutch as im ready to shift to second

if i punch it from a dead stop it does not make any knock sound.

any help guys.

car drives great and pulls hard.

and no i do not launch the car.

thanks in advance

Check if the mounts are tight. Possibility of transmission slack???
