I had that exact set up at one time with a manual boost controller, I swapped to the KB 70mm and Plenum and gained 3psi of boost.
Then went to a V2 FMIC and gained another 3 3/4 pounds.
I do not have any 1/4 mile times or MPH to back anything up, but the fact it gave me back 3 psi of boost must mean there is some intake restriction its opening up. Felt good to me.
