So to go back to the filter question and R&D. I installed everything, ran no filter, and saw 12.6 psi. My tuner suggested that I put the filter on to protect from grime buildup and we would continue tuning. Yesterday I put the filter on and did some pulls. The most pressure I saw was 7.6 psi, giver or take .5 psi.

To recap:
Filter off: 12.6 psi
Filter on : 7.6 psi

I've had this kit on two cars now and I've threads showing how thoroughly I've searched for leaks or low boost pressure causes. It was this simple all along...

Also, to be clear, this is a fantastic kit! Aaron has done an awesome job! Like everything else, we just find ways to make it more efficient.
