Good point Patrick and that was the case which I corrected about 6 months ago, it was opening 80-85% but not much improvement. I even wired the vac sec closed and not a great deal different, the most I can get them to open is about 85% with the lightest spring. It feels more like a potent small block.
Incoming I don’t really want to do burnouts, I am just using that as a gauge if you will, I run 25 psi.
