BIG.... but seriously it's probably an 8LB

6LB is 9.1", 8LB is 9.55"

What pulley you running up top, hopefully something close to stock...

On an Eaton that's crazy! Do you have a boost gauge? Even on my Posi Port I was weary of running a 2.93/6# stuck to a 2.93/4# kind of agreed upon as the best Eaton combo. 2.8/8# is close to if not 20 psi and you're not getting much over a 2.93 or 2.8 with a 4# but extra heat.

Posi and/or Jake (BADASS03SVT) did some testing and even with a 2.93/6# he wasn't really going any faster than the 4# and would be heated up after a single pass.

Should i go ahead and change the 8lb lower to a 4

I would definitely think about it... surprised no one else has offer opinions. Who ported it and who tuned it, tuner should have noticed that'd not a great set up if it is in fact an 8# which is what Lethal's site says.
