34mm Flapper

[DSM9119]

Anyone using the 34mm wastegate flapper? Did it make a sizable differance? Are you using it unported or ported? How was instalation? I'm cutious before I decide to pick one up.

I have one on my Big 16g. The wastegate hole was ported to match. I didn't do the install, so you might want to go to vfaq.com for install instructions to see if you can handle it.
Just getting the big flapper without porting the hole bigger will be worse because it will restrict flow around the edges of the flapper, which are now wider.
I don't get boost creep at all, and I run from 12 psi up to 25 psi.
